The product of <span>2x^2+6x-8 and x+3 is:
= (</span><span>2x^2+6x-8)(x+3)
= 2x^3 + 6x^2 - 8x + 6x^2 + 18x - 24
= 2x^3 + 12x^2 + 10x - 24
This answer can still be simplified by dividing everything by 2
= x^3 + 6x^2 + 5x - 12
So the product of </span>2x^2+6x-8 and x+3 is equal to <span>x^3 + 6x^2 + 5x - 12.</span>
Answer:
<em>6</em><em> - 5</em><em> + 1</em>
Step-by-step explanation:
Standard form is:
To reach that you have to distribute:
(2x - 1) (3x - 1)
2x (3x - 1) = 6 - 2
-1 (3x - 1) = -3 + 1
Combine like terms:
6 - 5 + 1
If two triangles are similar, that means their side lengths are proportional.
Now we want to find side PQ, so let us set up some proportions:
So x = 30.
Hope that helps!

I brlive that is the answer
Answer: negative 6
Step-by-step explanation:
Since at the top of the mountain its already 0 and the degrees drop 3 each hour then multiply -3 by 2 hours and there you go.
