Mr. Gonzalez is designing a planter box. The width will be 3 feet, and the height will be 2.5 feet. The length will be 1.5 feet. What expression gives the volume of the planter box in cubic feet?

2.5 feet*3 feet*1.5 feet=11.25 cubic feet

Step-by-step explanation:

the volume of a cube is equal to the length times the width times the height and since the length is 1.5 feet, height is 2.5 feet and width is 3 feet you just multiply them and get 11.25 cubic feet or 11.25 feet^3.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

the answer is  

a.
