Answer:

4(x+1)(x-2)

Step-by-step explanation:

factor the expression: 4x^2-4x-8

4(x^2-x-2)

write as a difference: 4(x^2+x-2x-2)

factor out x: 4(x(x+1)-2(x+1)),

then factor out x+1:

Answer:

A, C, F

Step-by-step explanation:

JK is proportional to PQ, so that would be 8/x. Then, JL is proportional to PR, which would be 10/5. So, the answer is: 8/x = 10/5

Then, C would also be correct as KL is proportional to QR, and JK is proportional to PQ.

Finally, F is correct as JK to KL is proportional to PQ to QR, as JK is proportional to PQ, and KL is proportional to QR.
