Abby’s Expression:
Double m, giving 2m. She then takes 20% of the result, which we can write 0.2(2m). Finally she subtracts this from 2m, giving 2m−(0.2)2m
2m − (0.2)2m

Answer:
Length:
11
Width:5
Step-by-step explanation:
Let's say x is the width, then length is 3x-4
Area of a rectangle is Length times width
so x(3x-4)=55
then we solve
3x^2-4x-55=0
(3x+11)(x-5)=0
x cannot be negative so x=5
then if the width is 5, length is 3*5-4=11
