2{x}^{2}+3x-2x-32x2+3x−2x−3

2 Factor out common terms in the first two terms, then in the last two termsx(2x+3)-(2x+3)x(2x+3)−(2x+3)
3 Factor out the common term 2x+32x+3(2x+3)(x-1)(2x+3)(x−1)

Find the average of the following salaries: $38,750.00, $42,500.00, $44,500.00

sertanlavr [38]

To find the average you add all three numbers together and then divide by three since you added three.
$38,750.00 + $42,500.00 + $42,500.00 = $123,750.00
$123,750.00 ÷ 3 = $41,250
So your answer is $41,250

My grade is a 77%, if i get a 0% on a paper worth 30% of my grade, what will my grade be now??

blsea [12.9K]

$Grade=Paper+Other$
$Grade=(Grade_{paper}\times Value_{paper})+(Grade_{other}\times Value_{other})$
$Grade=(0 \times 30\%)+(77\% \times (1-30\%))$
$Grade=(0 \times 30\%)+(77\% \times 70\%)$
$Grade=0+53.9\%$
$Grade=53.9\%$
