-x+40=28
-x=-12 (subtract 40 from both sides)

Divide by -1(in both sides)because you cant have a negative age.
COLE is 12 

 To check plug in the values.

What is the volume of the rectangular prism?
Mkey [24]
The answer to this problem would be B. Here are the steps:
So, the dimensions of the prism are: 9,3, and 7.
Multiply them all: 9×3×7=189
Lastly: you multiply 189×1/3=63 yd^3
Incase you are wondering, since each cube is 1/3 in length you multiply that by the volume of the prism.
Hope this helps (:
