Answer:
I believe it's parrolelegram rectangle and square
C and D.If I'm right,can u make me the brainliest answer?Thank You.
Answer is: Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 20.2
First you add 3 and 2 so that is 5 and then you subtract 5 from 9 so the answer is 4.
Answer:
x = 4 ± 
Step-by-step explanation:
Given
(x - 12)(x + 4) = 9 ← expand the left side using FOIL
x² - 8x - 48 = 9 ( ad 48 to both sides )
x² - 8x = 57
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = 57 + 16
(x - 4)² = 73 ( take the square root of both sides )
x - 4 = ±
( add 4 to both sides )
x = 4 ±
