Answer:
For #5
Step-by-step explanation:
Perpendicular
I think the answer is x>-28
Answer:
A
Step-by-step explanation:
Given
x² - x = 30
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(-
)x +
= 30 + 
(x -
)² =
Take the square root of both sides
x -
= ±
= ± 
Add
to both sides
x =
±
, thus
x =
-
= - 5
x =
+
= 6
