2. Identify the error in generating an expression equivalent to 4 + 2x-3(10-4x). Then correct the error.
4 + 2x + z(10 +- 4x)4 + 2x +- 5 + 2x4 + 2x-5 + 2x - 1
Identify the error
Correct the error.

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

ummm seems that u didnt post the attachement !

just sum

10 + 10 = 20
