Answer:
20
Step-by-step explanation:
Here are some solutions: (there are actually an infinite amount of them)
x = 0 , y = 7
x = 1 , y = 8
x = 2 , y = 9
x = 3 , y = 10
x = 4 , y = 11
x = 42 , y = 49
x = pi , y = pi + 7
birkkkkkkkkkkkkkkkkkkk
48
x/8+3=9
x/8=9-3
x/8=6
x=6*8
x=48
D) 8x²-172x+120
Length=2(-2x+20)+6
Width=-2x+20
(-4x+40+6)(-2x+20)
(-4x+46)(-2x+20)
8x²-80x-92x+920
8x²-172x+920
