-40 + 2x = 4x - 8(x+8)
-40 + 2x = 4x - 8x - 64
-40 + 64 = 4x - 8x - 2x
24 = -6x
x = 24 / -6
x = -4

Answer:

$x = - 4$

Step-by-step explanation:

$-40 + 2x = 4x - 8(x + 8) \\ 2x - 40 = 4x - 8x - 64 \\ 2x + 8x - 4x = 40 - 64 \\ 6x = - 24 \\ x = - \frac{ 24}{6} \\ x = - 4$

This graph relates the volumes of triangular pyramids with a base area of 12 square inches and their heights.

Nikolay [14]

Answer:

$V=40\ in^3$

Step-by-step explanation:

The graph is not attached, however we know that, the volume of a triangular pyramid is given by the formula

$V=\frac{1}{3}Bh$

where

B is the area of the triangular face

h is the height of the pyramid

we have

$B=12\ in^2\\h=10\ in$

substitute the given values

$V=\frac{1}{3}(12)(10)=40\ in^3$
