Answer:
12 cm is the width
Step-by-step explanation:
The perimeter of a rectangle is given by
P = 2(l+w)
We know the perimeter is 44 and the length is 10
44 = 2 (10+w)
Divide each side by 2
44/2 = 2/2 (10+w)
22 = 10+w
Subtract 10 from each side
22-10 = 10-10 +w
12 = w
The width is 12
(y-3)^2 -4y +12 = 0
[y^2 -6y +9] -4y +12 =0
y^2 -10y + 21 = 0
(y -3) (y-7) =0
y=3 ; y = 7
2x+2 would be the expression
