Question
The local swimming pool is rectangular and the length is 5 feet more than twice the width If the area of the pool is 1375 square feet then what are the length and width of the pool
Answers
Reiny
width ---- x
length ---- 2x+5
x(2x+5) = 1375
2x^2 + 5x - 1375 = 0
solve the quadratic
hint: it factors, but it may be just as fast to use the formula
