Answer:
a) The polynomial is equivalent to 
, and the side length of the playground is 
feet.
b) The perimeter of the playground, measured in feet, is 
.
Step-by-step explanation:
a) By Geometry, we know that area of the square is equal to the square of the side length. If 
is the area of the square, then must be a perfect square trinomial, that is:
(1)
Then, we must observe the following properties:
(2)
(3)
Therefore, the polynomial is equivalent to , and the side length of the playground is feet.
b) The perimeter of a square equals four times the side length. That is:
The perimeter of the playground, measured in feet, is .
Answer:
9.2 ounce
Step-by-step explanation:
To do this, we divide $12 by 16 ounces, because there are 16 ounces in a pound:
12/16 = 0.75
Now, we need to find how many ounces can be bought for $4.80. To do this, we divide 6.90 by 0.75
=9.2 ounce
Answer:
1) $16.32 per lap
2) $19.17 per lap
3) $23.25 per lap
Step-by-step explanation:
simply divide the total amount of money by the number of laps
EX:
2) 230 divided by 12 = 19.17
it is 22.91 because you add all the sneakers and then after all that you add the tax
The point on the number line represents C) 
.
Step-by-step explanation:
Step 1:
The distance between 0 and 1 is split into 4 partitions.
The value for each distance is given by dividing the difference by the number of partitions; 
So each partition represents a value of 
Step 2:
The value of the first partition; 
,
The value of the second partition; 
The value of the third partition; 
,
The value of the fourth partition; 
The point on the number line is in between the zero and the second partition so it is the first partition which has a value of
