As seen in the diagram below, Madelyn is building a walkway with a width of a feet to
julsineya [31]

Applying the area of a rectangle, the width of the walkway (x) is: 4 feet.

<h3>What is the Area of a Rectangle?</h3>

Area of a rectangle = (length)(width)

Total area of the pool and walkway = 300 sq. ft

Length of the pool and walkway = 12 + 2x

Width of the pool and walkway = 7 + 2x

Thus, we will have the equation of the total area as:

(12 + 2x)(7 + 2x) = 300

4x² + 38x + 84 = 300

4x² + 38x + 84 - 300 = 0

4x² + 38x - 216 = 0

Factorize

(x - 4)(2x + 27) = 0

x = 4

or

x = -27/2

The width, x, cannot be negative, so, the width of the walkway (x) would be 4 feet.

One number is times a first number. A third number is 100 more than the first number. If the sum of the three numbers
icang [17]

When a number is 3 times a first number. A third number is 100 more than the first number and the sum of the three numbers is 450, the numbers are 70, 170 and 210.

<h3>How to calculate the numbers?</h3>

Let the first number = x

Second number = 3x

Third number = x + 100

Sum = 450

The numbers will be:

x + 3x + x + 100 = 450

5x + 100 = 450

5x = 450 - 100

5x = 350

Divide

x = 350 / 5

x = 70

First number = 70

Second number = 3x = 3 × 70 = 210

Third number = x + 100 = 70 + 100 = 170

Therefore, the numbers are 70, 170 and 210.
