Write an algebraic expression for the perimeter of the swimming pool

Mathematics
1 answer:
Pachacha [2.7K]3 years ago

Answer: I don't see that you have a diagram of the swimming pool or any given side measures but assuming it is a rectangle, the algebraic expression would be 2(L+W) where L is the length and W is the width.

Step-by-Step Explanation: So when you are finding the perimeter, you are finding the length of the space surrounding something. So you would add up the length of all its sides to find it. In a rectangle, opposite sides are equal, therefore the length will be equal to the side opposite to it and the width will also be equal to the side opposite to it. So if you were to write the expression like that, you would get L+L+W+W, which can be simplified to 2L+2W, or just 2(L+W).

The sum of the measures of the interior angles in a convex polygon is 1,260°. How many sides does the polygon have?
gavmur [86]
The formula for working out the total interior is:

180(n-2) = 1260

So let’s rearrange by dividing both sides by 180 and find what n is:

n-2 = 7

Then let’s add 2 to both sides to find what n is:

n=9

Each interior angle is 1260/9 = 140°.
The sum of the interior angle and its corresponding exterior angle is 180°.

Therefore, the polygon has 9 sides. :)

Answer:

y = 4x-9

Step-by-step explanation:

16x-4y-36 = 0

-4y = -16x+36(subtract 16x from both sides and add 36)\

y = 4x-9(divide both sides by -4)
