Answer:
+ 
Step-by-step explanation:
To complete the square, with the coefficient of the x² term = 1
add ( half the coefficient of the x- term)² to both sides
x² + 3x + (
)² = 6 + (
)²
x² + 3x +
= 6 + 
Answer:
A = pi * r^2 = pi * 5^2 = 25*pi = 78.54 in²
8x - 3x - 7 = 23
5x - 7 = 23
5x = 30
x = 30/5 = 6
I think the answer would be -$22.27 because 89.08 divided by for is 22.27
