What is 3 times 567 rounded to the nearest hundred?

Good evening ,

3×567 = 1 701

1 701 rounded to the nearest hundred : 1700.

:)

Okay so we're given:

 Area = x^2 + 5x -84
width = x +12
We need to find length, so for now, let's say length = L

We know Area = Length x Width so filling what we have into this equation...

Area = Length*width

x^2 +5x -84 = L*(x+12)

Divide both sides by (x +12) and you get...

(x^2 +5x-84)/(x+12) = L

Do that division and you get

L = x-7

Let me know if you need help with the polynomial division, there are lots of good videos on it on youtube!
