Answer:

r = 13

Step-by-step explanation:

The first step is to find b from y=mx=b using m=4/3 and (-4,8)

8=\frac{4}{3}(-4)+b

After solving the equation, b will equal -16/3 making the final equation be

y=\frac{4}{3} x-\frac{16}{3}

Using the equation, you can solve for r.

12=\frac{4}{3} x-\frac{16}{3}

This will bring the answer being r = 13

A reflecting pool is shaped like a square with a side length of 4 meters. What is the perimeter of the​ pool? Explain how you fo
True [87]

Answer:

16 meters.

Step-by-step explanation:

There are two things to keep in mind at this point, the first is that a square has all its sides equal and the second is that the perimeter in this type of figure is the sum of all the sides.

Knowing the above, we can deduce that therefore each side of the square measures 4 meters and the perimeter could be calculated since we know the value of all the sides, we know that a square has four sides:

p = 4 +4 +4 +4

p = 16

that is to say that the perimeter is equal to 16 meters.
