The answer is letter B. Because you have to distribute:
-3(6x+7)+4(7x+2) equals
-18x-21+28x+8
then you add all the x terms: -18x+28x=10x
next you add up the numbers without an x term:-21+8=-13
SO, the answer is 10x-13
-3(6x+7)+4(7x+2) equals
-18x-21+28x+8
then you add all the x terms: -18x+28x=10x
next you add up the numbers without an x term:-21+8=-13
SO, the answer is 10x-13
