L=length, w=width
l=2w+5
2l+2w=34
2l=4w+10 [here I just multiplied the first equation by two]
4w+10+2w=34 [substitute 4w+10 for 2l]
6w=24, w=4
remember l=2w+5 so l=2(4)+5=13

Answer: The length is 13.

A rectangular photograph has an area of 65 square inches. If the length of the photo is 3 inches less than twice it's height, fi

tankabanditka [31]

A = L * H
A = 65
L = 2H - 3

65 = H(2H - 3)
65 = 2H^2 - 3H
-2H^2 + 3H + 65 = 0
(-Hh + 13)(H + 5) = 0

-2H + 13 = 0
-2H = -13
H = -13/-2
H = 6.5 <== height is 6.5 inches

H + 5 = 0
H = -5....this wont work because it is negative

L = 2H - 3
L = 2(6.5) - 3
L = 13 - 3
L = 10 <== length is 10 inches
