Factor the following expression using the GCF.
4dr – 16r

r(4d – 16)
2r(2d – 8)
4(dr – 4r)
4r(d – 4)

Step-by-step explanation:

is found in both numbers, so is the GCF.

What is divided by ? It would be .

What is divided by ? .

So, our equation now looks like this:

So, the last one is correct.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
