Answer:

x^2-5x+6\\(x-3)(x-2)

x^2-3x+4\\(x-4)(x+1)

x^2+20x+100\\(x+10)(x+10)\\(x+10)^2

That's the answer

x^2+14x-49\\x(x+14)-49

Only x^2+20x+100 is a perfect square trinomial

m_a_m_a [10]

Answer:

$33

Step-by-step explanation:

From the question, $22 is correct

If Helen Ming receives travel allowance of $220 from her company for time away from home

She has a 10% income tax rate

The amount she has to pay in taxes for the employee benefits is

10% of $220

10/100*$220

=0.1*$220

=$22

So you are correct

The only reason why you could be wrong is if the question is different from what you posted above just like the below question

Helen Ming receives a travel allowance of $220 each week from her company for time away from home. If this allowance is taxable and she has a 15 percent income tax rate, what amount will she have to pay in taxes for this employee benefit?

Here the amount she has to pay for the employee benefits is

15% of $220

15/100*$220

=0.15*$220

=$33
