1. Gross pay= monthly salary+commission

Commission = 9652*0.03 = 289.56

Gross pay = 2985+289.50 = $3274.56

2. The FICA withholding amount for the employee is 7.65% of gross income wherein 6.2% is for Social Security and 1.45% is for Medicare.

So, FICA tax = $\frac{7.65}{100}*2190= 167.535$

3. Total earnings of Carol = 642.20+115.34+62.75 = $820.29

So, her hourly wage = $\frac{820.29}{37} =22.17$

Hence, Carol's hourly wage is = $22.17

Factor the polynomial 4x4 – 20x2 – 3x2 + 15 by grouping. What is the resulting expression?

siniylev [52]

Factoring the polynomial $4x^4-20x^2-3x^2 + 15$ by grouping means separation of the polynomial in two addends, each of them consists of two addends:

$4x^4-20x^2-3x^2 + 15=(4x^4-20x^2)+(-3x^2+15).$

In first brackets the common factor is $4x^2,$ in second brackets the common factor is $-3.$

Then

$(4x^4-20x^2)+(-3x^2+15)=4x^2(x^2-5)-3(x^2-5)=(x^2-5)(4x^2-3).$

Answer: correct choice is B
