Answer:

5 and 6

Step-by-step explanation:

-5 x 6 = -30

-5 + (6) = 1

x2 + 1x - 30 = 0

(X - 5 ) (X + 6)

To summarize, since -5 and 6 multiply to -30 and add up 1, you know that the following is true:

x2 + 1x - 30 = (X - 5 ) (X + 6)

Explanation:

Calculation for What is his monthly taxes

First step is to calculate the Gross monthly income

Gross monthly income=Annual salary/Numbers of months in a year

Let plug in the formula

Gross monthly income=$13,500/12 months

Gross monthly income=$1,125

Therefore the Gross monthly income is :$1,125

Monthly Federal income tax (11.6%): $130.50

($1,125*11.6%)

Monthly Social security (FICA) (6.2%): $69.75

($1,125*6.2%)

Monthly Medicare (1.45%): $16.3125

($1,125*1.45%)

Monthly State Tax (4%): $45

($1,125*4%)

Monthly Local Tax (0.1%): $1.125

($1,125*0.1%)

Total Monthly deductions $262.6875

($130.50+$69.75+$16.3125+$45+$1.125)

Trey’s NMI $862.3125

Trey’s NMI=Gross monthly income-Total Monthly deductions

Trey’s NMI=$1,125-$262.6875

Trey’s NMI=$862.3125

Gross monthly income:$1,125

Monthly Federal income tax (11.6%): $130.50

Monthly Social security (FICA) (6.2%): $69.75

Monthly Medicare (1.45%): $16.3125

Monthly State Tax (4%): $45
