You simplefie them and get 1/2 for 4/8
2/3 for 8/12
3/4 cannot be somplified
Answer:
it should be -8 and -65 you would use parentheses first then you would have the negative integers in it's place
Here we have one large triangle with two smaller triangles drawn inside. The two smaller triangles are similar.
Thus, a/12 = 12/16, or a/12 = 3/4, or 4a=36, or a = 9.
Find b in the same way: b/20 = 9/12 (and so on).
