Need help with this math problem​

choice 2) x+2y+3 = 7

Step-by-step explanation:

equation to match:

x+2y = 4

add 3 to each side

x+2y+3 = 7      (which is the same as choice 2, x+2y+3 = 7)

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
