Question 3 (5 points)
the length of a rectangular poster is 10 inches longer than the width. if the perimeter of the poster is 124 inches, what
is the width?

width = 26 inches

Step-by-step explanation:

perimeter of a rectangle= p

p= 2*L+ 2*w

L= length

w= width

The statement tell us:

L= 10+w

p=124

124=2*(10+w) +2*w

124= 20+2w+2w

124-20=4w

w=104/4

w=26 =width

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
