Factor by using the rational roots test, and find that -2 is a root.

Replace X with -2 and simplify each term.

Divide the polynomial by (x+2)

The final answer becomes x = -2 and x = -1/2 +/-√3/2i

The first choice is the correct one.

Answer:

AB = JK = 49

Step-by-step explanation:

Since ABC = JKL

We know the length of AB has to equal the length of JK.

AB = JK

14x+7 = 5x+34

Subtract 5x from each side.

14x-5x +7 = 5x-5x+34

9x+7 = 34

Subtract 7 from each side

9x+7-7 = 34 -7

9x = 27

Divide each side by 9.

9x/9 = 27/9

x =3


AB = 14x+7

Substitute x=3

      14(3) +7

      42+7

AB =    49
