4y(3y + 9)
12y + 36
36 ÷ 12=x=3
A= l*w
168= 14*w
Divide both sides by 14
168/14= 14w/14
12=w
Final answer: 12 ft (I'm not sure if you meant to switch the order of b and c).
X varies directly as y
x = ky
3 = 2k
k =

when x =9
9 =

y

= y
∴y = 6

If you would like to solve the equation k / 2 + 9 = 30, you can calculate this using the following steps:
k / 2 + 9 = 30
k / 2 = 30 - 9
k / 2 = 21 /*2
k = 21 * 2
k = 42
The result is 42.
