The sum of the area of these three rectangles will be 3x² + 20x.

<h3>What is the area of the rectangle?</h3>

Let L be the length and W be the width of the rectangle.

Then the area of the rectangle will be

Area of the rectangle = L×W square units

The lengths and the widths of the following three rectangles are labeled.

The area of the first rectangle will be

A₁ = x · x

A₁ = x² square units

The area of the second rectangle will be

A₂ = 20 · x

A₂ = 20x

The area of the third rectangle will be

A₃ = 2x · x

A₃ = 2x²

Then the sum of the area of these three rectangles will be

A = A₁ + A₂ + A₃

A = x² + 20x + 2x²

A = 3x² + 20x

Thus, the sum of the area of these three rectangles will be 3x² + 20x.

More about the area of the rectangle link is given below.

Determine whether each relation is a function. Give the domain and range for each relation.
brilliants [131]

Answer:

Not a function

Domain: {3,4}

Range: {4,5}

Step-by-step explanation:

A function is a relation where each input has its own output. In other words if the x value has multiple corresponding y values then the relation is not a function

For the relation given {(3, 4), (3, 5), (4, 4), (4, 5)} the x value 3 and 4 have more than one corresponding y value therefore the relation shown is not a function

Now let's find the domain and range.

Domain is the set of x values in a relation.

The x values of the given relation are 3 and 4 so the domain is {3,4}

The range is the set of y values in a relation

The y value of the given relation include 4 and 5

So the range would be {4,5}

Notes:

The values of x and y should be written from least to greatest when writing them out as domain and range.

They should be written inside of brackets

Do not repeat numbers when writing the domain and range
