Step-by-step explanation:
5+5=10
2/2=1
Answer:
x = 20
Step-by-step explanation:
Let W=width of parking lot,
then Length = W+3
Total area = W(W+3)=550
Exapand and express in standard quadratic form
W^2+3x-550=0
Factor
(W+25)(W-22)=0
Therefore W=22 or W=-25, reject negative root, so
Width = 22'
Length=22+3=25'
Check: (area = 22' * 25'=550 sq. ft, ok)
