Hey there!
I want you to think of radicals as like terms. In order to be able to combine like terms, you need the same base and exponent.
For example,
3x^2-y^2 <== same exponent but not same variable
3x^2-x^2 <=== could be combined because exponent (^2) and variable (x) are the same
So, for this question, you're looking for a radical that has 5 under the radical sign and 3 above the radical sign.
"B" is the right answer, because is ∛ and in the radical it has a √5.
I hope this helps!

How do I solve for X
Answers
Answer:
x = 140
Step-by-step explanation:
The figure is a quadrilateral. That means it has 4 sides and more importantly for this question 4 angles. All quadrilaterals have 4 angles that add up to 360o.
You know 3 of the angles. The fourth one is x.
90 + 90 + 40 + x = 360 Combine like terms on the left
220 + x = 360 Subtract 220 from both sides.
220 - 220 + x = 360 - 220 Combine all like terms
x = 140

there are 150 more passenger cars than trucks on the highway. for every 10 passenger cars there are 7 trucks. how many trucks are on the highway?
Answers
Answer:
500
Step-by-step explanation:
Given: P = 150 - T where P is passenger cars and T is trucks
10P = 7T ⇔ P = [tex]\frac{7T}{10}[/tex]
Plug in equation 2 into equation 1:
[tex]\frac{7T}{10}[/tex] = 150 - T
Solving for T, we get 500
Answer:
There would be 500 passenger cars and 350 trucks.
Step-by-step explanation:
In order to find this, we need to create a system of equations. Start by making the number of passenger cars as x and the number of trucks at y. Now the first equation can be the difference of the two.
x - y = 150
The second equation can make use of the proportion. If we multiply by the opposites we'll get the difference of 0.
7x - 10y = 0
Now we multiply the first equation by -10 and add together to solve for x.
-10x + 10y = -1500
7x - 10y = 0
-------------------
-3x = -1500
x = 500
Now we can find the amount of trucks by using either equation.
x - y = 150
500 - y = 150
-y = -350
y = 350

Sabrina needs $12,000 for her first year of college. Her mom has already saved $9,000. Sabrina has to pay the rest. She has 8 months to save enough money for her first year of college. How much does she need to save each month ?
Answers
Answer:
$375
Step-by-step explanation:
subtract 9,000 from the 12,000, then divide the 3,000 by 8 and you get 375.
She needs to save $375 each month. This is because the total she needed was $12,000 but her mom paid $9,000 which leaves $3,000 and she has eight months and 3,000 divided by 8 = $375

Answers
Answer: 16
Step-by-step explanation: If 3 black circles equal 30, we can divide that by 3 and get 10. If 1 black circle and 2 white circles equal 18, we can subtract 10 and get left with 2 white circles worth 8, which means a white circle is 4. A white circle minus a square is 2, which means a square is 2. So we put this all together and get 16.
The area of the base of a rectangular prism is 36 cm 2
square inches the height of the prism is 3 and 5/6 CM what is the volume of the prism
Answers
The volume of the rectangular prism is 138.48 cubic centimeters. It is calculated by multiplying the base area of 36 cm² with the height of 3 and 5/6 cm.
To find the volume of the rectangular prism, you need to multiply the area of the base by the height. The formula for the volume of a rectangular prism is:
Volume = Base Area × Height
Given:
Base Area = 36 cm²
Height = 3 and 5/6 cm
First, let's convert the height to an improper fraction:
3 and 5/6 = (6 × 3 + 5) / 6 = 23/6 cm
Now, plug in the values into the formula:
Volume = 36 cm² × 23/6 cm
To multiply, you can first simplify the fraction:
Volume = 36 cm² × 3.83 cm
Finally, calculate the volume:
Volume = 138.48 cm³
The volume of the rectangular prism is 138.48 cubic centimeters.

What is the y-intercept of y=-3-7r?
Answers
Answer:
y-intercept: -3Step-by-step explanation:
y-intercept is for r = 0.
We have the equation y = -3 - 7r.
Substitute r = 0:
y = -3 - 7(0) = -3 - 0 = -3
Other way.
The slope-intercept form of an equation of a line:
y = mx + b (y = mr + b).
m - slope
b - y-intercept
We have the equation y = -3 - 7r = -7r - 3. Therefore m = -7 and b = -3.

How would I simplify and solve for X in this trigonometric equation? (Radians)
[tex]cos(x+\pi )^{2} = sinx[/tex]
Answers
Answer:
Please, refer to the images below
Step-by-step explanation:
We need to solve for x in the equation
cos (x+ pi) ^2 = sin (x)
cos (x+ pi) = - cos(x)
(-cos (x)) * (-cos (x)) = sin(x)
cos(x) ^2 = sin(x)
We know that
cos(x) ^2 + sin(x) ^2 = 1
cos(x) ^2 = 1 - sin(x) ^2
1 - sin(x) ^2 = sin(x)
sin(x) ^2 + sin (x) -1 = 0
Let A = sin(x)
A^2 + A - 1 = 0
(solutions attached in picture 1)
This means that

 Question:
The time required for a skilled worker to produce x shirts is given by the function T(x) = 4x + 2, where T is measured in hours. The salary the she is paid is given by the function S(T) = 15T, where S is measured in dollars.
A. If the worker produces 18 units, what will she be paid?
B. How many units would the worker need to produce to be paid $3,030?
Answers
Answer:
A) The worker is paid S= $ 1110 for producing 18 units.
B) The worker is paid $3,330 for producing x= 50 units.
Step-by-step explanation:
a) given x = 18 units
Time required T(x) = 4x+2
= 4(18)+2
= 72 +2
= 74 hrs
Amount paid S(T) = 15 T
= 15 ( 74) = $ 1110
b) Since S is given, S= $3,030
S(T)= 15 (T)
3030 /15= T
202 hrs= T
Now, we can find x:
T(x) = 4(x) +2
202 = 4x + 2
202-2 = 4x
200 / 4 =x
50 = x
so, worker produces 50 units.
