Question 1133450
Charlotte has appointed a chairperson to lead a city beautification project. The first act is to install statues and fountains in one of the city's parks.
 The park is a rectangle with an area of 
91x^2 + 57x − 18 m^2 as shown in the figure below.
 The length and width of the park are perfect factors of the area.
:
91 only has one pair of factors 13 & 7
(13x - __)(7x + __)
Factors of 18, 9 & 2 and 6 & 3, try them both,
(13x - 3)(7x + 6) seems to work, if you foil
91x^2 + 78x - 21x - 18 = 91x^2 + 57x - 18
then
(13x - 3) and (7x + 6) are the length and width of the park
