Use the substitution method for y=0
(40,0)
y=0
0=0
Answer: (40,0) It does make the equation y=0 true
The cost of dryer is $450 and the cost of washer is $412
2w + 2l = 25
2 * 2 + 2l = 25
<em><u>Simplfiy.</u></em>
4 + 2l = 25
<em><u>Subtract 4 from both sides.</u></em>
2l = 21
<em><u>Divide both sides by 2.</u></em>
l = 10.5
Now that we have the value of l, we can find the area.
A = lw
A = 10.5 * 2
A = 21.
The length is 10.5cm.
The area of the rectangle is 21cm^2
20+64=84 40+44=84 74+10=84 30+54=84
