Answer:

Step-by-step explanation:

AC = 64
AB = 7x + 8
BC = 3x + 6

<u>Since AC = AB + BC</u>

7x + 8 + 3x + 6 = 64
10x + 14 = 64
10x = 50
x = 50/10
x = 5

------------------

BC = 3x + 6 = 3*5 + 6 = 21

Answer:

(-3, 8)

Step-by-step explanation:

For m the midpoint of xy, we have ...

m = (x+y)/2 ⇒ y = 2m-x

y = 2(4, 3) -(11, -2) = (2·4 -11, 2·3 +2)

y = (-3, 8)
