C = d × pi
C = 6 × 3.14
C = 18.84
<span>-5x < 35

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.
Answer:
Hi, there your answer will be C.
Step-by-step explanation:
The reason why is because X(Input) can not be repeated the same
for example the coordiante( 1,3) and (1,4). See there are two ones which make them not function
Also, if you're having trouble with Functions and nonfunctions
REMEMBER THS
Function: X and y has to be separarte and can't have the same X
NON-FUNCTION- WHEN X REPEATS ITSELF
Hope this helps :)
