Question

Barry had a rectangular farm with dimensions x feet and 20 feet. He put a fence along 30 feet of the boundary of the farm.

An expression is shown below:

(2x + 40) - 30

Part A: What does the expression represent? (4 points)

Part B: What does 2x + 40 represent? (3 points)

Part C: What does 2x represent? (3 points)

Answer 1

Part A: represents how much more of the rectangle that he has to put fence around
Part B: represents the dimensions of the rectangle
Part C: represents the unknown amount of feet times 2 because to find the dimensions of the rectangle you use the formula 2l x 2w. Because you don't know the amount of feet, you just leave it as 2x.

Answer 2
