Let x be the width
Lenght = 10x + 8.1
(10x + 8.1)2 + 2x = 515.6
22x = 499.4
x = 22.7
Area = l*w
= 22.7*235.1
= 5336.77
= 5340( nearest tens)
Point slope form is an equation to graph lines.
Answer:

I got 3.33 because I just set the problem up as
4x+5=x+15
and then I did
4x-x=3x
and then I did
15=3x+5
and then
15-5=10
and then
3x=10
then
10÷3=3.33
