Answer the following questions. Leave in simplest terms.

13. Find the area of a rectangle with a length of (5x + 1) inches and a width of (3x - 2) inches.

Answer 1

Area = length x width
Area = (5x + 1)*(3x - 2)
Area = 5x*3x + 5x*-2 + 1*3x + 1*-2
Area = 15x^2 - 10x + 3x - 2
Area = 15x^2 - 7x - 2 :)
