Hello,
Let's to remember,
To the perfect square:
X^2 +12x = -6
We would have to add 6^2
Because,
X^2 + 2.(6X) = -6
As (x+k) = x^2 +2xk +k
And,
2xk = 2.6x
xk = 6x
K = 6
Then,
(X+k)^2 = x^2 + 2xk+k^2
= x^2+2.x.6+6^2
= x^2+6x+36
We would to add 36, and would stay:
X^2 + 6X = -6
x^2 +6x + 36 = -6 +36
X^2 +2.6x +6^2 = 30
(X+6)^2 = 30
Answer is the letter A)

Answer: Stephen's net income is $921.71
Step-by-step explanation:
Hi, to answer this question, first, we have to multiply the amount of hours worked (112) by 11 (because he earns $11 per hour)
Mathematically speaking:
112 x 11 = $1,232
Now we have to sum the federal income tax ($216.05),Social Security ($76.38), and Medicare ($17.86) to obtain the total expenditures:
Total expenditures: $216.05 +$76.38 +$17.86 = $310.29
Finally we subtract the total expenditures ($310.29) to Stephen's revenue ($1,232) to obtain Stephen's net income.
Net income = 1,232 - 310.29 =921.71
Stephen's net income is $921.71
According to me D could be the right answer..but not sure about it
