Answer:

2x^3 + 2x^2 - x - 10

Step-by-step explanation:

(f + g)(x) = f(x) + g(x)

f(x) + g(x) = x^3 + x^3 + 2x^2 - x - 10

Combine like terms.

f(x) + g(x) = 2x^3 + 2x^2 - x - 10

Since we made it clear that f(x) + g(x) = (f + g)(x)...

(f + g)(x) = 2x^3 + 2x^2 - x - 10

What percent of 25 is 7?<br><br> And<br><br> What number is 21% of 300?
Hunter-Best [27]

This is for the first one 85.714286%



This is for the second one


olution for 21 is what percent of 300


100%/x%=300/21

(100/x)*x=(300/21)*x - we multiply both sides of the equation by x

100=14.2857142857*x - we divide both sides of the equation by (14.2857142857) to get x

100/14.2857142857=x

7=x

x=7


now we have:

21 is 7% of 300

ivanzaharov [21]

Alright, lets get started.

At the beginning of her training, she is able to run 2 miles without stopping means 2 will be in the addition when we will write the equation for her running miles.

Her goal is to increase her distance by three quarters of a mile each week.

Means in first week, she will add the distance = \frac{3}{4} miles

Suppose she runs x weeks, so shee will add distance = \frac{3}{4}x

So, suppose she runs total number of miles = d, then

d = 2 + \frac{3}{4}x

Where d is total numer of miles she runs

x is number of weeks    :   Answer

Hope it will help :)
