Answer:

12ft

Step-by-step explanation:

A prism is a 3D shape which has the same 2D shape repeated along its length (this is sometimes called the cross section).

The 2D shape at the ends of the prism is the base of the prism, so for this shape, the <u>bases</u> are the <u>triangles</u>.

The height of the prism is actually the length of the prism, so for this prism the height is 12 ft.

Find y if 1030404(3y+36) = 1030403(3y+36).
MA_775_DIABLO [31]

For this case we have the following equation:

1,030,404 (3y + 36) = 1,030,403 (3y + 36)

We apply distributive property to the terms within parentheses:

3,091,212y + 37,094,544 = 3,091,209y + 37,094,508

We subtract 3,091,209and on both sides of the equation:

3,091,212y-3,091,209y + 37,094,544 = 37,094,508\\3y + 37,094,544 = 37,094,508

We subtract 37,094,544on both sides of the equation:

3y = 37,094,508-37,094,544\\3y = -36

We divide by 3 on both sides of the equation:

y = - \frac {36} {3}\\y = -12

Answer:

y = -12
