The blanks are as follows:
- Angle addition postulate
- Subtraction property of equality
- Corresponding sides of similar triangles are proportional
- Multiplication property of equality
X - 2 = -5
x = -5 + 2
x = -3
(x-2)^2 + 5x - 10...when x = -3
(-3-2)^2 + 5(-3) - 10
-5^2 - 15 - 10
25 - 15 - 10
10 - 10
