Volume of a cube is s^3, where s is the length of a side.
Volume = 7 ^3
Volume = 343 cubic inches.
Answer:
13
Step-by-step explanation:
3 - 9 = -6
-6 + 18 = 12
-9 * -2 = 18
12 - 8 = 4
4 + 16 = 20
-8 *-2 = 16
20 - 7 = 13

Answer: 21
4/7 = 12/x
Multiply each side by x, so the x drops out on right side:
(4/7)x = 12
Distribute x:
4x/7 = 12
Multiply each side by 7, so the 7 drops out on left side:
4x = 84
Divide:
x = 84/4
x = 21
Answer: 1st one: x^2, when x greater than or equal to -1
2nd one: 4, when -1 < x < 2
3rd one: 2x+1, when x less than or equal to 2
