Check the picture below.

\bf \textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=2.9 \end{cases}\implies C=2\pi (2.9)\implies C=5.8\pi \implies C\approx 18.22 \\\\[-0.35em] ~\dotfill\\\\ ~\hfill \stackrel{C\div r}{18.22\div 2.9 \approx 6.28}\qquad \stackrel{C\div d}{18.22\div 5.8 \approx 3.14}~\hfill

Can you help me with this please
Shalnov [3]

Answer:

  see below

Step-by-step explanation:

If (x+5) is a factor of p(x), then the value x=-5 will make that factor be zero. The product p(x) of which it is a part will also be zero, so p(-5) = 0.

Since p(-5) = 0 at x=-5, there will be an x-intercept at x=-5.

Dividing something by a factor of that thing will always give a remainder of zero. So, p(x)/(x+5) has a remainder of 0.
