The length of a rectangle is 3 inches less than twice the width. If the perimeter of the rectangle is 18 inches, find the width
of the rectangle
1 answer:
Answer:
y = 4. So this is your width.
Step-by-step explanation:
Use the distributive property to do 2(2y-3) = 2*2y-2*3 = 4y-6. So we have
4y-6+2y = 18. Combine like terms 4y and 2y to get 6y.
6y-6 = 18. Add 6 to both sides to solve for 6y
6y = 24. Divide by 6 to solve for y
y = 4. So this is your width.
length = x

Volume of a cube is S^3
S is the width.
Volume = 8^3 = 512 cubic feet.
Because the volume of a cube with side length 8 feet = 512 cubic feet, the prism could be a cube.
