Answer:

p = -1.

Step-by-step explanation:

By the Remainder Theorem the remainder when  x- 3 is divided into f(x) is

p(3)^3 + 4(3)^2 + 3(3) - 4  =   27p + 41.

The remainder when x^3 - 4x + 9 is divided by  x- 3 = 27 -12 + p =  15 + p.

So 27p + 41 = 15 + p

26p = - 26

p = -1.

Find the percent of 30$ board game on sale for 20.10$
inessss [21]
Easy, use these two formulas, to find Markdown:

Markdown=Original-New
and
Markdown%=\frac{Markdown Amount}{Original Selling Price} *100

So, plug in what you know.

Markdown= $30-$20.10
M=$9.90

Now, Markdown%

Markdown%=\frac{9.90}{30} *100
M%=0.33*100
M%=33

Thus, there was a 33% markdown.
