Answer:
21
Step-by-step explanation:
8 * 2 = 16
5 * 2 = 10
68 - 16 = 52 - 10 = 42.
The perimeter of the square is 42.
42 / 4 = 10.5. 10.5 is the length of a side.
10.5 * 2 = 21.
I think (jk) (x) means j times k
(jk) (x) = -7x(9 - 2x) //Using Distributive Property.
(jk) (x) = -63x + 14x^2 = 14x^2 - 63
//Hope it helps.
