Answer:
Length = 28 m
Width = 15 m
Step-by-step explanation:
Court is rectangular in shape.
Now, we are told that;
Length is 2m less than twice the width(W) .
Thus;
Length; L = 2W - 2
We are told the perimeter is 86 m.
Formula for perimeter of a rectangle is;
P = 2(L + W)
Thus;
2((2W - 2) + W) = 86
Divide both sides by 2 to get;
(2W - 2) + W = 43
3W - 2 = 43
3W = 43 + 2
3W = 45
W = 45/3
W = 15 m
Thus; L = 2(15) - 2
L = 30 - 2
L = 28 m
Answer:
point M and line f
Step-by-step explanation:
Answer: The answer is 7 ( x + 3 ).
Step-by-step explanation:
So we are given in word-form this equation:
seven times the sum of a number and three
We can rewrite this as:
7 times ( number + 3)
This number can be rewritten as a variable. Take any variable of your pick. I'll use x because that's one of the most used variables.
7 ( x + 3 )
There you go! Finished.
Answer:
x = -4 and -2x - 8
Step-by-step explanation:
<u>Step 1: Distribute</u>
-1/3(6x + 15) - 3
-6/3x - 15/3 - 3
-2x - 5 - 3
-2x - 8
<u>Step 2: IF NEEDED SOLVE FOR X</u>
-2x - 8 + 8 = 0 + 8
-2x / -2 = 8 / -2
x = -4
Answer: x = -4 and -2x - 8
Answer:
The area of the pool is: 365.025 squared feet
Step-by-step explanation:
Given
--- Length
--- Width
Required
The area of the pool
The area of an oval shape (i.e. the pool) is:
![Area = \pi ab](https://tex.z-dn.net/?f=Area%20%3D%20%5Cpi%20ab)
Where
![a = \frac{L}{2}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7BL%7D%7B2%7D)
![b = \frac{W}{2}](https://tex.z-dn.net/?f=b%20%3D%20%5Cfrac%7BW%7D%7B2%7D)
So, we have:
![Area = \pi * \frac{L}{2} * \frac{W}{2}](https://tex.z-dn.net/?f=Area%20%3D%20%5Cpi%20%2A%20%5Cfrac%7BL%7D%7B2%7D%20%2A%20%5Cfrac%7BW%7D%7B2%7D)
![Area = \pi * \frac{31}{2} * \frac{15}{2}](https://tex.z-dn.net/?f=Area%20%3D%20%5Cpi%20%2A%20%5Cfrac%7B31%7D%7B2%7D%20%2A%20%5Cfrac%7B15%7D%7B2%7D)
![Area = \pi * \frac{465}{4}](https://tex.z-dn.net/?f=Area%20%3D%20%5Cpi%20%2A%20%5Cfrac%7B465%7D%7B4%7D)
![Area = \pi * 116.25](https://tex.z-dn.net/?f=Area%20%3D%20%5Cpi%20%2A%20116.25)
![\pi = 3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D%203.14)
So:
![Area = 3.14 * 116.25](https://tex.z-dn.net/?f=Area%20%3D%203.14%20%2A%20116.25)
