(x + 9)² = 36
Step-by-step explanation:
Given
x² + 18x + 57 = 12 ( subtract 57 from both sides )
x² + 18x = - 45
To complete the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(9)x + 81 = - 45 + 81
(x + 9)² = 36

I GOT THE POWER OF GOD AND ANIME ON MY SIDE
OKOK
A salesperson averaged $120 per 10 days sooo 120/10 is 12 so about 12 per day
So,
You guess the amount that could make up a number around 150or 160
So 12 x3 = 36 + 120=156 hallelujah!
So, 3 more days until she can average $160 in order to bring her overall average to 150%.....
Hope this helps. :::)))))
