Answer:
Length = 7 Width = 2
Step-by-step explanation:
L = Length
W = Width
L=9w-11
2L+2W=18
2(9W-11) + 2W = 18
18W - 22 +2W = 18
20W -22 = 18
20W = 40
W = 2
L = 9(2)-11
L=18-11
L=7
Step-by-step explanation:
x2 + 7x + 12
x2 + 4x + 3x + 12
x(x + 4) + 3( x + 4)
(x + 3) and (x + 4) are the factors
4x2 + 6x + 2
4x2 + 4x + 2x + 2
4x (x + 1) + 2(x + 1)
(x + 1) and (4x + 2) are the factors
