The solution to the system of equations is where the two functions intersect (cross each other). the point the do that is closest to (1,2)
Is there a picture of the question? 2 13 pencils and 3 34 minutes doesn't make sense
A=63
L=2w+5
A=LW
63=(2W+5)*W
63=2W^2+5W
2W^2+5W-63=0
(2W-9)(W+7)=0
2W-9=0
W=9/2
W=4.5 (ANS. FOR THE WIDTH)
L=2*4.5+5
L=9+5
L=14 (ANS. FOR THE LENGTH)
PROOF:
63=14*4.5
63=63
Have a nice day :D
