Answer:
8
Step-by-step explanation:

A----------D----------C
AD = 2x + 6
DC = 4x - 7
the midpoint D splits AC into 2 equal parts....therefore, AD = DC
2x + 6 = 4x - 7
2x - 4x = -7 - 6
-2x = - 13
x = -13/-2
x = 6.5
DC = 4x - 7......4(6.5) - 7 = 19 <===
AD = 2x + 6.....2(6.5) + 6 = 19
Answer:
(x+8)^2=0
Step-by-step explanation:
x^2+16x+64=0
8x8=64
8+8=16
Therefore, 8 fits
(x+8)^2=0
