Question

Melanie's bedroom floor has length equal to 6x + 5 and width equal to 9x – 2 points

4. What equation represents the area of the floor?

Answer 1

(6x+5)(9x-2)

Explanation:

Area = Length x Width

Answer 2

54
`x^(2)` +33x - 10

Explanation:

you have to use F.O.I.L. First Outter Inner Last

(6x + 5)(9x - 2)

First (6x)(9x) = 54
`x^(2)`

Outter (6x)(-2) = -12x

Inner (5)(9x) = 45 x

Last (5)(-2) = -10

combine middle terms

54
`x^(2)` +33x - 10
