Substitute the value n = 4 in the expressions<br><br>2n<br>n + 2<br>3(n+4)

Lelu [443]

Step-by-step explanation:

Given n = 4

2n = 2* 4= 8

n + 2 = 4 + 2 = 6

3(n + 4) = 3( 4 + 4) = 3 * 8 = 24

Hope it will help :)

The length of a rectangle is 2x – 3 feet, and the width is 5 feet. What is the area of the rectangle in square feet?

dimaraw [331]

The area of a rectangle is length times width or base times height

so 5 times 2x-3

if you multiply them together 5(2x-3) you would get 10x-15

there is no value of x

so the area would be 10x-15ft^2

If f(x) =4x^2 + 1 and g(x) =x2 -5, find (f+g)(x)

Lilit [14]

The value of $(f+g)(x)$ is $5 x^{2}-4$

Explanation:

Given that the functions $f(x)=4 x^{2}+1$ and $g(x)=x^{2}-5$

We need to determine the value of $(f+g)(x)$

The value of $(f+g)(x)$ can be determined by substituting the value of $f(x)$ and $g(x)$ and simplifying the terms.

Thus, let us assign $f(x)=4 x^{2}+1$ in the function $(f+g)(x)$ , we have,

$4 x^{2}+1+g(x)$

Now, let us assign $g(x)=x^{2}-5$ in the function $(f+g)(x)$ , we get,

$4 x^{2}+1+x^{2}-5$

Grouping the like terms, we have,

$4 x^{2}+x^{2}+1-5$

Adding the like terms, we get,

$5 x^{2}-4$

Hence, the value of $(f+g)(x)$ is $5 x^{2}-4$
