What is the value of x?

Answer:

12. AM= 2x+4

MB= 5x-8

AB= ?  

So to get AB, you would need to find the total measurements of AM and MB.  

AM=MB  

2x+4=5x-8

2x=5x-12

-3x=-12

x=4

20. AE= 37

21. AC=  16

Step-by-step explanation:

Answer:

18 yds

Step-by-step explanation:

Let the length and width be L and W respectively.

Then L· W = area = 72 yd², so that L = (72 yd²) / W.

But also L = 3W + 6 yd.  Subbing this into  L· W = area = 72 yd², we get:

(3W + 6) · W = 72, or

3W² + 6W - 72 = 0.  Since all  four terms are evenly divisible by 3, we get:

W² + 2W - 24 = 0, which factors as follows:

(W + 6)(W - 4) = 0.  Then W + 6 = 0, or W = -6 (makes no sense for a length), and W - 4 = 0 yields W = 4 yds.

If the shorter side is of length 4 yds, then the longer side is of length

L = 3(4 yds) + 6 yds = 18 yds

Answer:

18 yd

Step-by-step explanation:

(3x + 6) * x = 72

Use the distributive property

3x^2 + 6x = 72

3x^2 + 6x - 72 = 0

3(x^2 + 2x - 24) = 0

X^2 + 2x - 24 = 0

X can equal -6 and 4.

4 only works for this problem

4 * 3 = 12

12 + 6 = 18

So, the answer is 18 yd.

Let’s check our work.

3 * 4 = 12

12 + 6 = 18

18 * 4 = 72

So, we know for a fact that the longer side is 18 yd long.

According to the information, it can be inferred that the current credit score for Esteban is 730 because he has not used more transactions than eleven of his credit score.

A credit score is a term that refers to an index that is intended to predict the chances that you will repay a loan on time.

This takes into account different factors related to your economy, so it is likely that the more movement of money you have, your score will be higher.

Based on the foregoing, it can be inferred that Esteban's score dropped because he has not made important transactions in recent months. Additionally, it has no recent transaction history.

Note: This question is incomplete due to missing information. Here is the complete information:

Answer: True

Step-by-step explanation:

 We know that the quadratics polynomials have this form:

[tex]f(x)=ax^2+bx+c[/tex]

You need to remember that the degree of a polynomial is given by its highest exponent.

You can observe in the quadratic polynomial [tex]f(x)=ax^2+bx+c[/tex] that the highest exponent is "2", which is the exponent of the term [tex]ax^2[/tex]

Therefore, since the highest exponent is "2", you should conclude that the degree of the polynomial is 2.

Then, you can say that a quadradic polynomial has degree 2.

Answer:

let X represent the number of spider.

8x+6*(x+1)=160

8x+6x+6=160

14x=154

x=11

x+1=11+1=12

So the number of ants is 12, the number of spiders is 11.  

Step-by-step explanation:

I'm not the best at math, but I tried.

x= the amount of months passed

The question asks for the population of fleas in 1 year, and 1 year = 12 months, then x would equal 12 months

Therefore, you substitute that x with 12

f(x)=250(2^x)-------f(x)=250(2^12)

Now you can solve that part of the problem:

2 to the power of 12= 4096

f(x)=250(4096)

now multiply that:

250×4096= 1024000

The answer is C. 1024000

The answer is 1,024,000 fleas.

The function f(x)=250(2^x) gives the population of fleas after x months. To find out how many fleas there will be after 1 year, substitute x=12 into the function:
f(12) = 250(2^12) = 250 * 4096 = 1,024,000 fleas.

Hyperbola:

[tex]x^2-y^2-8x+6y-1=0[/tex]

Step-by-step explanation:

the given hyperbola has equation:

This is an equation of a hyperbola centered at the origin.

This hyperbola is translated so its center is now at T(4,3)

[tex](x-4)^2-(y-3)^2=8[/tex]

Answer:

1=0.84 per gallon

2=5.25 per lb

Step-by-step explanation:

Divide the cost or amount by how many of what there is. Ex= 10.5/2=5.25

The answer is:

The total time traveled is equal to 9 hours.

To solve the problem, we need to write two equations using the given information about the travel upstream and downstream.

So, we need to write two equations:

Let be "x" the speed of the cabin cruiser (12 mph in still water)

Let be "y" the speed of the current (4 mph).

Then,

For the travel against the current (upstream), we have:

[tex](x-y)*t_{upstream}=48miles\\\\(x-y)*t_{upstream}=48miles\\\\(x-4mph)*t_{upstream}=48miles[/tex]

For the travel with the current (downstream), we have:

[tex](x+y)*t_{downstream}=48miles\\\\(x+y)*t_{downstream}=48miles\\\\(x+4mph)*t_{downstream}=48miles[/tex]

Also, we know that the speed of the cruise traveling in still water is equal to 12mph.

So,

Calculating the time traveled upstream, we have:

[tex](x-4mph)*t_{upstream}=48miles[/tex]

[tex](12mph-4mph)*t_{upstream}=48miles[/tex]

[tex](8mph)*t_{upstream}=48miles[/tex]

[tex]t_{upstream}=\frac{48miles}{8mph}=6hours[/tex]

Calculating the time traveled downstream, we have:

[tex](x+4mph)*t_{downstream}=48miles[/tex]

[tex](12mph+4mph)*t_{downstream}=48miles[/tex]

[tex](16mph)*t_{downstream}=48miles[/tex]

[tex]t_{downstream}=\frac{48miles}{16mph}=3hours[/tex]

Now that we know the time traveled upstream and downstream, we need to calculate the total time traveled using the following equation:

[tex]TotalTime=t_{upstream}+t_{downstream}\\\\TotalTime=6hours+3hours=9hours[/tex]

Hence, we have that the total time traveled is equal to 9 hours.

Only one pair has the second number 4 more than the first: 10 and 14.

Since you are given variable definitions, perhaps you're expected to write and solve equations.

  a + b = 24 . . . . . the sum of the two numbers is 24

  -a +b = 4 . . . . . . the second number is 4 more than the first

Adding these two equations gives ...

  (a +b) +(-a +b) = (24) +(4)

  2b = 28 . . . . .  simplify; next, divide by 2

  b = 14 . . . . . . .  identifies 10 and 14 as the correct answer

3.4(x+1.58)= - 11.288

Step 1: Distribute 3.4 to the numbers inside the parentheses (x+1.58)

3.4x + (3.4×1.58)= - 11.288

3.4x + 5.372 = -11.288

Step 2: Bring 5.372 to the right side by subtracting it to both sides

3.4x + (5.372 - 5.372 ) = (-11.288 - 5.372)

3.4x + (0) = (-16.66)

3.4x = -16.66

Step 3: Isolate x by dividing 3.4 to both sides

[tex]\frac{3.4x}{3.4}  = \frac{-16.66}{3.4}[/tex]

x = -4.9

In the given problem, the amount of pence that Jill has can be expressed in terms of x (the amount of pence that Jack has) as x - 6. This means Jill has 6 pence less than Jack. If Jack has a certain number of pence represented as x, then Jill would have that number minus 6.

The question asks for the amount of pence that Jill has in terms of x, where x is the amount of pence that Jack has. Given that Jill has 6 pence less than Jack, we can represent the amount of pence Jill has as x - 6. Therefore, if Jack has x pence, Jill would have x - 6 pence. For example, if Jack (x) has 10 pence, Jill would have 4 pence (x - 6 = 10 - 6).

ANSWER

C. 145.75 yd²

EXPLANATION

First we need to calculate the area of the four triangular faces.

The lateral surface area

[tex] = 4 \times \frac{1}{2} \times 5.3 \times 11.1[/tex]

[tex] = 117.66 {yd}^{2} [/tex]

The area of the base is

[tex] = 5.3 \times 5.3[/tex]

[tex] = 28.09[/tex]

To find the total surface area, we add the area of the square base to the area of the 4 triangular faces.

Therefore the total surface area is

[tex] = 117.66 + 8.09 = 145.75 {yd}^{2} [/tex]

Answer: Option C.

Step-by-step explanation:

To calculate the surface area of the right square pyramid, you need to use the following formula:

[tex]SA=\frac{1}{2}(4s)(l)+(s^2)[/tex]

Where  "s" is the length of any side of the base and "l" is the slant height.

You can identify in the figure that:

[tex]s=5.3yd\\l=11.1yd[/tex]

Therefore, substituting these values into the formula, you get this result:

[tex]SA=\frac{1}{2}(4(5.3yd))(11.1yd)+((5.3yd)^2)\\\\SA=145.75yd^2[/tex]
