You need to use the distributive property and distribute 2.
multiply 2 by 3x then 2 by 5
youll now get 6x+6x+10- 9
simplify that again and you'll be done

The functions f(x)=√x^2+12x+36 and g(x)=x^3-12 are defined below. Which expression is equal to f(x) · g(x)? A.x^4-6x^3-12x+72 B.
Lostsunrise [7]

Answer:

C: x^4+6x^3-12x-72

Step-by-step explanation:

For the function : f(x)=√x^2+12x+36

It can be factorized to

f(x)=√(x+6)²

=x+6

f(x)*g(x)

=(x+6)(x^3-12)

Expand the brackets

=x^4-12x+6x^3-72

rearrange the numbers

x^4+6x^3-12x-72

What is the solution (x,y) to the system of equations given? 2 x + 4 y = − 16 2x+4y=−16 2 y − x = = 16 2y−x==16
alisha [4.7K]

Answer:

(-12,2)

Step-by-step explanation:

2x + 4y = -16

2y - x = 16

Multiply the bottom part by 2.

2x + 4y = -16

4y - 2x = 32

Add the equations and the answers to the equations up, and they will equal each other.

(2x + 4y) + (4y - 2x) = -16 + 32

8y = 16

y = 2

Plug y = 2 to the 2nd equation.

2*2 - x = 16

4 - x = 16

Subtract 4 from both sides.

-x = 12

Multiply both sides by -1.

x = -12

Answer:

<h2><em><u>15.71 is the perimeter.</u></em></h2>

Step-by-step explanation:

Perimeter = Circumference

<em><u>Step 1. Know and recognize what you have</u></em>

C = pi*d

pi = 3.142

d = 10

<em><u>Step 2. Solve for the circumference of whole circle</u></em>

C = 3.142*10

C = 31.42

<em><u>Step 3. Solve for the questions answer</u></em>

C of semicircle = 31.42/2

<h2><em><u>C of semicircle = 15.71</u></em></h2><h2><em><u></u></em></h2>

Hope this helped,
