Answer :- 

the quotient is ( 4x² - 5x + 7 )

Step-by-step explanation:

[ Refer to the attachment for steps ]

We have to eliminate the highest degree coefficient in each step.

And as in division of normal numbers we subtract the things here we do the same ,

but while subtracting we have to take care about the signs !

The negative sign changes the negative sign into positive sign and positive sign into negative sign.

Whereas , a positive sign don't changes the sign.

Answer:

$n^2 -3n - 6$

Step-by-step explanation:

Looking at the image attached, you must first work out the difference between each term. This is +0, +2, +4, +6, +8, +10 (shown in orange).

Because you now have a linear sequence, the difference is now the same each time. This is +2 (shown in blue).

Because the original sequence is a quadratic, you have to halve the second difference (the +2). This means that the value of $n^2$ is 1, so 1 $n^2$ or just $n^2$ .

If you write out the values of $n^2$ , you can work out how much more you need to add or take away. For example, take the first three terms in the sequence.

n = 1, 2, 3

x = -8, -8, -6

$n^2$ = 1, 4, 9

Work out the difference between $n^2$ and x:

1 - -8 = 9

4 - -8 = 12

9 - -6 = 15

This gives you yet another linear sequence, 9, 12, 15.

Working out the formula for this, the difference is 3 each time, so it is 3n. The first value of n is 1, so 3n is 1. The difference is 6, so the formula for this linear sequence is 3n + 6.

Because $n^2$ is greater than x, you need to take 3n + 6 away from $n^2$ .

This gives $n^2$ - (3n+6), so the final answer is:

$n^2$ - 3n - 6.

How do I find the area when given the circumference?

Ghella [55]

Im not sure if this is the answer due to how you asked your question

but if you want to know the circumference to that circle the answer is
A~ 0.096
hope this is right :)

The figure below shows a line graph and two shaded triangles that are similar:

Evgen [1.6K]

Answer:here is something to keep in mind.

when there is a downward slope, the slope will ALWAYS have a negative slope. even if it is above the x-axis. negative slopes will tend to go from positive y-axis to negative y-axis

so personally would have to go with -4

because the x-axis is by 4 each time. and this slope is going downward.

your answer will be D

It’s due tonight I would appreciate the help

tatuchka [14]

If you divide both sides of your inequality by five, you see that k must be less than 9

k < 9 that is equivalent.

You can make another equivalent inequality by multiplying both sides by 3.

3k < 27
