The diagram below represents the measurements of Jennie’s yard. The yard’s width is x feet shorter than its length. If the area of the yard is 540 square feet, how many feet shorter than the length is the width? Which equation represents the scenario?
A. 30 + (30 – x) = 540
B. 540 – 30 = 30 – x
C. 30(30 – x) = 540
D. 540 – (30 – x) = 30

Which represents the inverse of the function f(x) = 4x? h(x) = x + 4 h(x) = x – 4 h(x) = x h(x) = x
