Question

A regular skate park is 60 yards long and 50 yards wide. plans call for increasing both the length and the width of the park by x yards. Write a function l(x) that gives the new length of the skate park in terms of x. Write a function w(x) that gives the new width of the park in terms of x. what does (L*W)(x) represent in this situation? write and simplify the equation for (L*W)(x). Find (L*W)(x)

Answer 1

l(x) = 60 + x
w(x) = 50 + x

(L*W)(x) represents the area of the park.

(L*W)(x) = (60 + x)(50 + x) = 3,000 + 60x + 50x + x^2 = x^2 + 110x + 3,000
