We don’t know the value of the shorter side, so we will categorize it as x. Side 2 is just 4 feet longer than x, so we would add 4 on to it. Side 3 has double the x, so we would multiply it be 2 for 2x, and subtract the 4 feet from it.
Side 1: x
Side 2: x + 4
Side 3: 2x - 4
If the perimeter is 64 feet, then all of the sides have to add up to it. Therefore, first we add all of the side lengths up:
x + x + 4 + 2x - 4 = 4x.
Now we put 4x, the amount of all these sides added up, equal to the perimeter of 64.
4x = 64. Divide both sides by 4 to get x by itself.
x = 16.
Now that we know x is 16, we will substitute it in for all the side lengths’ equations.
We know that Side 1 was just x, so that will be 16. Since Side 2 was 4 more than x, we’d do 16 + 4 = 20. We substitute 16 in for x in Side 3’s equation: 2(16) - 4 = 32 - 4 = 28.
Therefore, the final lengths of all the sides are:
Side 1: 16
Side 2: 20
Side 3: 28
divide the total cost by the number of hinges:
Mark's hardware: $28 / 8 = $3.50 per hinge
Steve's Supply: $39 / 11 = $3.45 per hinge.
$3.45 is less than $3.50, so the answer would be C.

Answer: 100.8
Step-by-step explanation:
Given that:
Standard deviation (σ) = 16
X > 100
From the z table :
Zscore = P(X > 100) = - 0.05
Zscore = - 0.05
Thus ;
Zscore = (x - m) / σ
x = 100
-0.05 = ( 100 - m) / 16
-0.05 * 16 = 100 - m
- 0.8 = 100 - m
m = 100 + 0.8
Mean = 100. 8
Mean score = 100.8
