We use the FOIL method here. First, Outer, Inner, and Last.
(5x)(x) = 5x^2
(5x)(-7) = -35x
(2)(x) = 2x
(2)(-7) = -14
5x^2 - 35x + 2x - 14
Now combine like terms.
5x^2 - 33x - 14.
This is the right answer because it is now in the form of ax^2 + bx + c

yeah i guess you re right sorry for making confusion
A = πr² + πrl
306.00 = 3.14(6)² + 3.14(6)(l)
306.00 = 3.14(36) + 3.14(6l)
306.00 = 113.04 + 18.84l
- 113.04 - 113.04
192.96 = 18.84l
18.84 18.84
10.24 ≈ l
