The grassy area of a playground has a side length of x and a side of width of x + 3 what is the area of the playground?
Kipish [7]

Answer:

A

Step-by-step explanation:

We assume this playground is a rectangle. The area of a rectangle is of the form: A = lw, where l is the length and w is the width.

Here, the length is l = x and the width is w = x + 3. So, plug these in:

A = lw

A = x(x + 3)

Expand this out:

A = x² + 3x

The answer is thus A.

Function F(x)=x+1 and g(x)=5x+1 find the f(4)=g(x+1)
Lapatulllka [165]

The function of f(4) = g(x+1) gives the value of x that is -1/5.

<h3>What is the function addition?</h3>

It is the addition of two functions similar to the addition of any two polynomial functions.

Given;

F(x)=x+1

g(x)=5x+1

We need to find f(4)=g(x+1)

First substitute x = 4 in f(x)

F(x)=x+1

F(4) = 4 + 1

F(4) =  5

Now substitute x = x + 1 in g(x)

g(x)=5x+1

g(x + 1) = 5(x + 1) + 1

g(x + 1) = 5(x + 1) + 1

g(x + 1) = 5x + 5 + 1

g(x + 1) = 5x + 6

Then ,

F(4) = g(x + 1)

5 = 5x + 6

5x = 5 - 6

5x = -1

x = -1/5.

The function of f(4) = g(x+1) gives the value of x that is -1/5.
