Step-by-step explanation:
Step 1: Factor GCF
-1(x² - x - 42)
Step 2: Factor quadratic
-1(x - 7)(x + 6)
Answer:
(1/2) cm = x
Step-by-step explanation:
This box has the shape of a cube. The formula for the volume of a cube is V = x^3, where x is the length of any one side of the cube.
Here the volume is (1/8) cm^3. We set this equal to x^3 and solve for x:
Taking the cube root of both sides, we get:
(1/2) cm = x
Answer:
2 feet
Step-by-step explanation:
Since each piece of wood is 2/3 of a foot tall, and there are two pieces of wood stacked on top of each other, you need to add 2/3 twice to get the total height of the pile.
2/3 + 2/3 = 6/3
6/3 = 2
Therefore, the pile is 2 feet tall.
