X=7. The two segments on the bottom as well as on the diagonal are the same length. This shows that the entire triangle and the inner triangle on the right are similar. So if we call the length of the bottom 2y, then 84/2y=6x/y. Solving this we get 84=12x, and so x=7
80% of 7.5 is 6.
so if he travelled 80% further, it would be 7.5+6 which is
13.5
Answer: A 15
Step-by-step explanation:
To complete the square, you would add to both sides (8/2)^2 = (4)^2 = 16. So, the correct answer would be D.
