Answer:

$-x^3+7x^2-6x-18$

Step-by-step explanation:

Use distributive property: $(-x+3)(x^2-4x-6)$

What is -x * x^2? Answer: -x^3

What is 3 * x^2? Answer: +3x^2

What is -x * -4x? Answer: +4x^2

What is 3* -4x? Answer: -12x

What is -x * -6? Answer: +6x

What is 3 * -6? Answer: -18

$-x^3+3x^2+4x^2-12x+6x-18$

Combine like terms, and your answer would be....

$-x^3+7x^2-6x-18$

Hope this helps :)

Have a great day!

0 or 6x+4=6x+4 (Technically no slope at all!!)

Step-by-step explanation:

You need to do distributive property and then solve for x!!

meaning the 2(3x+2) has to get distributive property process.

6x+4=6x+4

That shall be equal together!!! (You could stop here!!)

If continue:

What's is the square root of 63

QveST [7]

You want to be finding out what two factors (where one of them is a perfect square) has the produce of 63. It seems like 9 x 7 (9 is the perfect square) works.

$\sqrt{63} = \sqrt{9 \times 7} = \sqrt{9} \times \sqrt{7}$

The square root of 9 is 3 so we can just have $3 \sqrt{7}$ (which just means 3 times the square root of 7).
