12 x 6 x 8 would be how you find the volume.

2 (12 x 6 + 2 x 12 x 8 + 2 x 6 x 8) would be to find the surface area.

I don't know about the rest.

Solve for x.
Simora [160]

Answer:

2 ≤ x ≤ 8

Step-by-step explanation:

This is a compound inequality and we are going to solve for x on both sides

For the first part,

0 ≤ 3x - 6

6 ≤ 3x

6/3 ≤ x

2 ≤ x

For the second part

3x - 6 ≤ 18

3x ≤ 18 + 6

3x ≤ 24

x ≤ 24/3

x ≤ 8

So the solution will be;

2 ≤ x ≤ 8

54 + 54 = 108, and 72 + 180 equals 180 degrees.

This is due to the fact all angles in a triangle add up to 180 degrees.
