Answer:
4
Step-by-step explanation:
Set up ratios of corresponding sides. x+2 is to 6 as 2 is to 3:

Now cross multiply to get
3(x + 2) = 12 and
3x + 6 = 12 so
3x = 6 and
x = 2. That means that side AB, x + 2, is 2 + 2 which is 4
About three times. Just divide 74 by 20 which is 3 but exactly it is 3.7.

Answer:
I am not 100% sure, however 6x-8=10 add 8 to both sides then youĺl get 6x=18 you divide 6 on both sides, then x will = to 3. I hope this helps
