Simplify the first fraction:
\frac{3n^{2}-n}{n^{2}-1} =  \frac{3n(n-1)}{(n+1)(n-1)} =  \frac{3n}{n+1}

Your equation becomes:
\frac{3n}{n+1} +  \frac{n^{2} }{n+1}  \\ = \frac{n^{2} + 3n}{n+1}  \\ =  \frac{n(n + 3)}{n+1}

That last fraction becomes your final answer.

A rectangle is 4xcm wide and 2cm long what do you notice
deff fn [24]

The width of the rectangle is twice the length of the rectangle

<h3>How to compare the dimensions of the rectangle?</h3>

The given parameters are:

Width = 4 cm

Length = 2 cm

Express 4 cm as 2 * 2 cm

Width = 2 * 2 cm

Substitute Length = 2 cm in Width = 2 * 2 cm

Width = 2 * Length

This means that the width of the rectangle is twice the length of the rectangle

Hence, the true statement is that the width of the rectangle is twice the length of the rectangle

If f(x) = x+3 and g(x) = VX-1,<br> what is (fºg)(26)?
scZoUnD [109]

Answer:

26V + 2

Step-by-step explanation:

This is the same as saying f(g(x)), where x = 26

First, lets figure out what g(x) is equal to when x = 26

g(26) = V(26) - 1 = 26V - 1

Now we input 26V - 1 into f(x) for x

f(26V-1) = (26V-1) + 3 = 26V + 2

Given f(x)=3x-1 find f(-1)
vaieri [72.5K]

Answer:

<h2>f( - 1) = - 4</h2>

Step-by-step explanation:

f(x) = 3x - 1

To find f(-1) substitute the value of x that's

- 1 into f(x). That's for every x in f(x) replace it with - 1 and solve

That's

f( - 1) = 3(-1) - 1

= - 3 - 1

We have the final answer as

<h3>f(-1) = - 4</h3>

Hope this helps you
