Answer:
y²-2y+3
Step-by-step explanation:
We write the dividend, y³-y²+y+3, under the box and the divisor, y+1, to the left of the box.
We first divide y³ by y; this is y². We write this above the box, over -y². We multiply the divisor by y²:
y²(y+1) = y³+y²
This goes under the divisor. We then subtract:
(y³-y²)-(y³+y²) = -2y². We then bring down the next term, y; this gives us -2y²+y.
We then divide -2y² by y; this is -2y. This goes above the box beside the y² in the quotient. We then multiply the divisor by -2y:
-2y(y+1) = -2y²-2y
We now subtract:
(-2y²+y)-(-2y²-2y) = 3y. We bring down the last term, 3; this gives us 3y+3. We divide 3y by y; this is 3. This goes beside the -2y in the quotient. We then multiply this by the divisor:
3(y+1) = 3y+3. We then subtract: (3y+3)-(3y+3) = 0
This makes the quotient y²-2y+3.

Last
First- 5x*2x=10x^2
Outer-5x*-1= -5x
Inner--7*2x= -14x
Last- -7*-1= 7
10x^2-5x-14x+7
you can simplify it further however thats the answer

Answer:
1.)
interval over which the difference of the numbers of sales is increasing: (<u>4.9, 10)</u>
interval over which the difference of the numbers of sales is decreasing: <u>(0, 4.9)</u>
interval over which the difference of the numbers of sales is positive: <u>(-9, -3)</u>
interval over which the difference of the numbers of sales is negative: <u>(-3, 10)</u>
<u />
2.)
The team’s total number of sales is equal to the average number of sales at
<u>-9, -3, and 10 </u>months from when Jared began gathering data.
The team’s minimum number of sales this year occurred at approximately
<u>-28</u> months from when Jared began gathering data.
3.)
