Answer:
D and E
Step-by-step explanation:
3(23+18)=123
6(18)=108. 6(19)=114. 6(20)=120. 6(22)=132. 6(24)=144
Step-by-step explanation:
x+90+4x-75=180
add all the sides together and since its a triangle they equal to 180
71 is the answer. If you round it, it would be 70.

The way I would do it is by rounding 8.91 up to 9 and I would round 34,871.081 up to 35,000.
9*35,000=315,000
Hopefully I was able to help in some way.
