Answer:

3(p + 2q)(p + 3q)

Step-by-step explanation:

Factor out 3 from each term

3(p² + 5pq + 6q²) ← factor the quadratic by

Consider the factors of the q² term which sum to give the coefficient of the pq- term

The factors are + 2 and + 6, since

2 × 3 = 6 and 2 + 3 = 5, hence

3p² + 15pq + 18q²

= 3(p + 2q)(p + 3q)

The quadratic expression [tex]3p^2+15pq+18q^2[/tex] can be factorized by first taking out a factor of 3, then factorizing the remaining quadratic expression. The result is 3(p+2q)(p+3q).

To answer your question about factorizing the quadratic expression [tex]3p^2+15pq+18q^2,[/tex] it's important we understand the factorization process.

First, we can take out a factor of 3.
So,[tex]3p^2+15pq+18q^2[/tex] = 3([tex]p^2+5pq+6q^2[/tex])

Now, we factor the quadratic expression [tex]p^2+5pq+6q^2.[/tex]
To factor it, we need to look for two numbers that multiply to 6 and add to 5. The numbers 2 and 3 fulfill this property. Therefore, we can write [tex]p^2+5pq+6q^2[/tex] = (p+2q)(p+3q)

So the factorization of the original expression is 3(p+2q)(p+3q)

The area of a trapezoid can be expressed as a polynomial using the formula a = 1/2h(b1+b2), where 'a' is the area, 'h' is the height, and 'b1' and 'b2' are the base lengths. If h=x, b1=y, and b2=z, then the polynomial expression for the area is a=0.5xz(y+z).

The area of a trapezoid can be expressed in the form of a polynomial by using the formula a = 1/2h(b1+b2), where 'a' represents the area, 'h' is the height of the trapezoid, and 'b1' and 'b2' are the lengths of the parallel sides. Expressing this as a polynomial expression, we could have variables in place of the height and side lengths, depending on the specific trapezoid. For example, if h = x, b1 = y, and b2 = z, then the polynomial expression for the area of the trapezoid becomes a = 0.5xz(y+z).

Answer:

-3x - 9y = 36

If x = 0

Step-by-step explanation:

1. Plug 0 to x:

-3(0) - 9y = 36

2. Simplify

0 - 9y = 36

3. Cross out the 0 to make the question faster to solve, which now you are left with:

-9y = 36

4. Divide both sides by -9:

-9y/-9 = 36/-9

5. Simplify:

y = -4 <--------Answer

Hope this Helped!!!!!

~Shane

The value of y when x equals 0 in the equation -3x - 9y = 36 is -4.

To find the value of y when x equals 0 in the equation -3x - 9y = 36, we can simply substitute 0 for x and solve for y.

Substituting 0 for x, the equation becomes:

-3(0) - 9y = 36

This simplifies to:

-9y = 36

Dividing both sides of the equation by -9, we get:

y = 36 / -9

This gives us:

y = -4

Therefore, the value of y when x equals 0 is -4.

explanation: if you don’t know how to factor gcf, look it up. But you need to find the gcf of 8 and 20 which is 4. Then you just get your answer. Sorry this is hard to explain but a tip is to distribute and check to see that it matches the original problem to find out if your answer is right. I will do that for this. 4(2x - 5) I use distributive property here meaning I distribute the 4 to both terms. 4 times 2x is 8x. 4 times negative 5 is negative 20. That leaves me with the original equation 8x - 20 so the answer is correct.

Answer:

Step-by-step explanation:

First, add 3 to both sides:

-5 = -6∛(x²)

Next, divide both sides by -6, to isolate ∛(x²):

5/6 = ∛(x²)

Eliminate the radical by cubing both sides:

5³

---- = x²

6³

Finally, take the square root of both sides.  This will isolate x.  There will be two roots:  one +, the other -.

x = ±√(5³/6³)

This simplifies to:  ± (5/6)∛(5/6).

Answer:

a. [tex]0.76,-0.76[/tex]

Step-by-step explanation:

The given equation is;

[tex]-8=-3-6\sqrt[3]{x^2}[/tex]

Add 3 to both sides of the equation to get;

[tex]-8+3=-3+3-6\sqrt[3]{x^2}[/tex]

[tex]\Rightarrow -5=-6\sqrt[3]{x^2}[/tex]

Divide both sides by -6.

[tex]\Rightarrow \frac{-5}{-6}=\sqrt[3]{x^2}[/tex]

[tex]\Rightarrow \frac{5}{6}=\sqrt[3]{x^2}[/tex]

Cube both sides of the equation;

[tex]\Rightarrow (\frac{5}{6})^3=x^2[/tex]

[tex]\Rightarrow \frac{125}{216}=x^2[/tex]

Take square root of both sides

[tex]\pm \sqrt{\frac{125}{216}}=x[/tex]

[tex]\pm 0.76=x[/tex]

[tex]\therefore x=0.76,-0.76[/tex]

Final answer:

The volume of the triangular pyramid is calculated using the formula V = 1/3 × base area × height. With a base area of 330 square yards and height of 18 yards, the volume is found to be 1,980 cubic yards. Therefore, the correct answer is C.

Explanation:

The volume of a triangular pyramid can be calculated using the formula V = 1/3 × base area × height. Given that the base area is 330 square yards and the height of the pyramid is 18 yards, we can calculate the volume by substituting these values into the formula: V = 1/3 × 330 × 18 = 1980 cubic yards. Therefore, the correct answer is C. 1,980 yd³.

The volume of the triangular pyramid is 1,980 cubic yards, making the correct answer option C.

To find the volume of the triangular pyramid, we first need to determine the area of the base triangle. Since the base has an area of 330 square yards, we can use the formula for the area of a triangle, which is 1/2 * base * height. Let's denote the base of the triangle as b and the height as h. We can rearrange the formula to solve for b:

[tex]\[ 330 = \frac{1}{2} \times b \times h \][/tex]

Given that the height of the pyramid is 18 yards, we can plug this value in and solve for the base:

[tex]\[ 330 = \frac{1}{2} \times b \times 18 \][/tex]

330 = 9b

[tex]\[ b = \frac{330}{9} \][/tex]

b = 36.67

Now, we have the base length of the triangle. Next, we can calculate the volume of the pyramid using the formula for the volume of a pyramid, which is [tex]\( \frac{1}{3} \times base\ area \times height \)[/tex]. Let's denote the volume as V:

[tex]\[ V = \frac{1}{3} \times 330 \times 18 \][/tex]

V = 1980

So, the volume of the pyramid is 1980 cubic yards. Therefore, the correct answer is option C: 1,980 yd.

Perpendicular is 0

Step-by-step explanation:

The line x = -42 is a vertical line through the x-axis. As such its slope is undefined. All parallel lines have the same slope and will also be undefined. Perpendicular lines will be lines horizontal through the y-axis. This means the slope of any perpendicular line to it will be 0.

The exponential function [tex]f(x)=2(3^x)[/tex] has an initial value of 2. The correct option is 1.

Step-by-step explanation:

The general form of an exponential function is

Where, a is initial value and b is growth or decay factor.

In option 1, the given function is

[tex]f(x)=2(3^x)[/tex]

Here, the initial value is 2 and growth factor is 3. Therefore the correct option is 1.

In option 2, the given function is

[tex]f(x)=3(2^x)[/tex]

Here, the initial value is 3 and growth factor is 2. Therefore option 2 is incorrect.
