Check the picture below.

\bf \textit{sum of all exterior angles in a polygon}\\\\ n\theta = 360~~ \begin{cases} n=\stackrel{number~of}{sides}\\ \theta =angle~in\\ \qquad degrees\\[-0.5em] \hrulefill\\ 0=45 \end{cases}\implies n(45)=360\implies n=\cfrac{360}{45}\implies \stackrel{\textit{an octagon}}{n=8}

Estimate the answer to<br> 64 x 186<br> 21 x 98
Vikentia [17]

Answer:

I am a bit confused on what the question is asking. But 64*186= 11904 and if we were to round that number it would be 12000. 21*98=2058 and that number rounded is 2100 or just 2000. (hope this is right and helps :D)

-2x^(3) +3=-1x^(3) -1x^(2) +1x+1
Natali5045456 [20]
-2x³ + 3 = -x³ - x² + x + 1

Add x³ to both sides, and subtract 3 from both sides.

-2x³ + x³ = -x² + x + 1 - 3

Add like terms.

-x³ = -x²+ x - 2

Move all of the (X's) to both sides, by adding x² to both sides, and subtracting x form both sides.

-x³ + x² - x = -2
