Answer:

Step-by-step explanation:
The area of a prism is given by the product of the base and the height. In this triangular prism, the area of the either base is:

The height is marked as
inches. Thus, the volume of the prism is:

Answer:
Step-by-step explanation:
A.
R(x)=px=x(-45 x+1800)=-45 x²+1800 x
B.
C(x)=7000+100 x
C.
P(x)=R(x)-C(x)=-45 x²+1800 x-(7000+100 x)
or P(x)=-45x²+1800 x-100 x-7000
or P(x)=-45 x²+1700 x-7000
Since x = -9, you substitue the X for -9.
your equation would then be y = |-9| +1
|x| is absolute vale and makes everything inside positive.
so really it is y = 9+1
y = 10
Answer x=-4
This would make a straight line going perpendicular to y=-3 and would pass through the point -4,3.
Answer:
Parimeter = (10 2/3 + 6 1/4 + 10 2/3 + 6 1/4) = 20 4/3 + 12 2/4
Parimeter = 21 1/3 + 12 1/2 = 21 2/6 + 12 3/6 = 33 5/6 ft
Amount of Wallpaper Border = 33 5/6 ft
