Alja [10]
If a binomial (x-a) is a factor of a polynomial, then a is a root of this polynomial.

(x+2)=(x-(-2)) \Rightarrow a=-2\\\\
(-2)^3-6\cdot(-2)^2+k\cdot(-2)+10=0\\
-8-24-2k+10=0\\
-2k=22\\\
\boxed{k=-11}

Use the given conditions to write an equation for the line in point-slope form.
Alex17521 [72]

Step-by-step explanation:

Hey there!

The given slope is; 3. And passing through point (-7,8).

Now,

Using one point formula.

(y - y1) = m(x - x1)

Put all values to find equation.

(y - 8) = 3(x + 7)

Simplify them to get answer.

(y - 8 )= 3x + 21

3x - y + 21 + 8 = 0

3x - y + 29 = 0

Therefore the required equation is 3x-y+29=0.

Answer:

QR = 5.

Step-by-step explanation:

Because the parallelograms are similar then the corresponding sides are in the same ratio.

So AB / PQ = BC / QR

9/3 = 15 / QR

15 / QR = 3

QR = 15/3

= 5.  (answer)
