Answer:
$1.22 per pair
The error is the contractor didnt take into account that there are 5 dozen gloves not 5 pairs of gloves. He calculated $73.20/5, which gave him $14.64.
Step-by-step explanation:
1 dozen = 12
5 dozen = 12 * 5 = 60
Therefore, you have 60 pairs of gloves.
He purchased all 60 pairs of gloves for $73.20.
73.20/60 = $1.22
This is how much one pair of gloves cost.
The expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.
<h3>What is the perimeter of a square?</h3>
The measure of the boundary of the sides of a square is called its perimeter. The perimeter of a square is 4 times the side of the square.

Here, (<em>a</em>) is the side of the square.
A square has a perimeter of 12x +52 units. The perimeter of a square is 4 times the side of the square. Thus, the side of this square is,

Thus, the expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.

Answer:
Step-by-step explanation:
find the area
Answer: ok
Step-by-step explanation:
Answer:
(m º n)(x) = x -2
Step-by-step explanation:
Here, in the given expression:
m(x)= x+1 and n(x) = x - 3
To find : (m º n)(x)
Now, solving for (m º n)(x)
(m º n)(x) = m (n (x)) = m (x-3)
also, m (x-3) = (x -3) + 1 = x -2
So, (m º n)(x) = x -2
