Answer:
should be 27 which is B so
To determine the amount of fencing needed to enclose the pool area, you will need to add 15 feet to both sides of both dimensions to find the new dimensions that will need enclosed.
28 feet + 15 feet + 15 feet = 58 feet
23 feet + 15 feet + 15 feet = 53 feet
The fence will need to be 2 x 58 + 2 x 53 or 222 feet long for the 53 feet by 58 feet area.
To solve this problem you must apply the proccedure shown below:
1. You have the following system of equation:

2. As you can see, you can cancel out the variable
, because it has equal coefficient with different signs at both equations. Then, if you add both equations, you obtain:

3. Let's substitute the value obtained into the second equation to calculate the other variable:

The answer is: (6,-6).
Answer:
A: 2, -2
Step-by-step explanation:
the first two represent the x axis and the negative two shows the y axis
<h2><u>Answer</u> :</h2>
The Answer is 2nd one
<h2><u>Explanation</u> :</h2>
<h3>Given :</h3>
- Radius of a circle = 11 cm
<h3>To Find : </h3>
- Circumference of the circle = ?
<h3>Solution :</h3>
As, we have radius of the circle is 11 cm and to find circumferemce, we have a formula :

By filling value of r = 11 cm and π = 3.14, we have :





Hence, circumference of the circle is 69.08 cm.
