Answer:
12???
Step-by-step explanation:
-10/8 and + 15/8. Those should work.
the 3rd vertex is on the x axis line which means Y =0
since the longer leg is twice as long as the shorter leg and the length of the shorter leg is a, then twice the length would be 2a ( 2 times a)
so the 3rd vertex is (2a,0)
The answer c, because they got 9 out of 15 flips being heads. This probability is 0.6. The other answers are not accurate.
