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

<u>Part A</u>
1) (5, -1)
2) (1, -3)
3) (-2, -2)
4) (-5, -4)
<u>Part B</u>
1) (-5, 1)
2) (-1, 3)
3) (2, 2)
4) (5, 4)
10(x^2) = 80x
(divide by the 10)
x^2 = 8x
which also equals
(x)(x) = 8x
(divide by x)
x = 8
