Answer:
x = -6
Step-by-step explanation:
Maybe this means you want to solve ...
-3x -8 = 10
-3x = 18 . . . . . add 8 to both sides
x = -6 . . . . . . . divide both sides by -3
If we assume Sam would achieve his aim of cutting the metal into 8 pieces.
Then he will make 8 cuts. It takes him 5 minutes to make each cut. This is how long it takes to make the cut. This only tells us that he will take a total of 8*5 = 40 minutes, to make all the cuts.
Sam will make 8 cuts as stated in the question.
Hint: Try using the Pythagorean thereom to solve it.
3.14 x 9^2 x 14/3 = 1186.92
4/3 x 3.14 x 9^3 = 1526.04
1186.92 + 1526.04 = 2712.96 = 2713 cubic inches
