Question

A firm is building a car park for its employees. Assume that a car park to accom-

modate x cars must have a length (in metres) of 4x +10 and a width of 2x +10. If

24 square metres will be specifically allocated for visitors’ cars, write an expres-

sion for the amount of space available for the cars of the workforce in terms of x

if x is the planned capacity of the car park.

Answer 1

$$(4x+10)(2x+10)-24$$

$$8x^2+40x+20x+100-24$$

$$8x^2+60x+76$$
