Answer:

105

Step-by-step explanation:

twenty more that the number n is 125 so n+20=125
subtract twenty on both sides
125–20=n
125–20=105
n=105

The wording is really word but I'm pretty sure this is correct

Which is larger 1000 feet or 300 yards?

Alexus [3.1K]

1 yard = 3 feet

300 yards = (3 ft) x (300) = 900 feet

<em>1,000 feet</em> is larger than 900 feet. It's also longer and farther.

Use synthetic division to find P (-10) for P(x)=2x^3+14x^2-58x

Savatey [412]

The polynomial remainder theorem states that the remainder upon dividing a polynomial $p(x)$ by $x-c$ is the same as the value of $p(c)$ , so to find $p(-10)$ you need to find the remainder upon dividing

$\dfrac{2x^3+14x^2-58x}{x+10}$

You have

..... | 2 ... 14 ... -58
-10 | ... -20 ... 60
--------------------------
..... | 2 ... -6 .... 2

So the quotient and remainder upon dividing is

$\dfrac{2x^3+14x^2-58x}{x+10}=2x-6+\dfrac2{x+10}$

with a remainder of 2, which means $p(-10)=2$ .
