Answer:
x = 2
x = 17
Step-by-step explanation:
Triangle ADC can be similar to AEB by property of similar angles (vertices are corresponding)
AC/AB = AD/AE
(10 + x)/10 = 18/15
15(10 +x) = 180
15x + 150 = 180
15x = 30
x = 2
Or
AD/AB = AC/AE
18/10 = (10+x) / 15
10(10+x) = 270
10x + 100 = 270
10x = 170
x = 17
Answer:
x^2 + 8x+16 is (x+4)^2
