a pool shaped like a rectangle prism is 40 feet long, 20 feet wide, and 4 deep. attached to the side of the pool is a hot tub wi

lubasha [3.4K]

Lets start with finding the volume of the pool

The formula for the volume of a rectangular prism is

V=l*w*h where l=length w=width and h=height
plug in the data we know
V=40*20*4
V=3200ft³

Now for the hot tub.

3200ft³*1/4=800ft³

Add the volumes together
3200+800=4000ft³

Answer=4000ft³

Consider the following pair of equations:

erastova [34]

y=-2x+8

y=x-1

Solve y=-2x+8 for y

Substitute -2x+8 for y in y =x-1

y=x-1

-2x+8=x-1

Add -x to both sides

-2x+8+-x=x-1+-x

-3x+8=1

Add -8 to both sides

-3x+8+-8=1+-8

-3x=-9

Divide both sides by -3

-3x/-3=-9/-3

x=3

Substitute 3 for x in y =-2x+8

y=-2x+8

y=(-2)(3)+8

Simplify both sides of the equation

y=2

Answer : y=2 and x=3

Does any one know the answer?

nekit [7.7K]

Answer: option C

find f(x) - g(x)

f(x)= $-9x^2 - 7x + 12$

g(x) = $3x^2 - 4x -15$

To find f(x) - g(x) we plug in the functions and subtract

$-9x^2 - 7x + 12- ( 3x^2 - 4x -15)$

Remove the parenthesis and change the sign of each term

$-9x^2 - 7x + 12 - 3x^2 + 4x +15$

Combine like terms

$-12x^2 - 3x + 27$

So option C is correct
