Answer:

 ≈ <em>3.4</em><em> </em>

Step-by-step explanation:

Coordinates of the point that divide segment with endpoints A( x_{1} , y_{1} ) and B( x_{2} , y_{2} ) in a ratio a : b are

\frac{bx_{1} +ax_{2} }{a+b} , \frac{by_{1} +ay_{2} }{a+b} )

A(- 4, - 7)

B(8, - 4)

Ratio 8 : 5

x-coordinate is \frac{5(-4)+8(8)}{8+5} = \frac{44}{13} ≈ <em>3.4</em>

Step-by-step explanation:

To calculate the midpoint, you need to plug in the values of x and y into the midpoint formula.

M ( x1 + x2/2 , y1 + y2/2)

M [ -8 + 4/2 , -7 + 9/2]

M ( -2, 1)

A rectangular swimming pool measures 7.5 m by 4.5 m. It is completely surrounded by a fence parallel to each edge of the pool an
Illusion [34]

The total length of the fence is 48 m if the rectangular swimming pool measures 7.5 m by 4.5 m.

<h3>What is rectangle?</h3>

It is defined as the two-dimensional geometry in which the angle between the adjacent sides are 90 degree. It is a type of quadrilateral.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

It is given that:

A rectangular swimming pool measures 7.5 m by 4.5 m.

It is completely surrounded by a fence parallel to each edge of the pool and at a distance of 3 m from each edge of the pool.

The total length of the fence = 2(7.5+3×2 + 4.5+3×2)

The total length of the fence = 2(7.5+6 + 4.5+6)

The total length of the fence = 2(24)

The total length of the fence = 48 m

Thus, the total length of the fence is 48 m if the rectangular swimming pool measures 7.5 m by 4.5 m.

Hey there!

To figure out what "x" means, you can divide the numbers 126 and 14  . . .

126 divided by 14 = 9

9 x 14 = 126

9 = x

----------------
x = 9
----------------

Hope this helps you.
Have a great day!
