The rule of PEMDAS states that Parentheses always comes first, exponents always comes second, but Multiplication and Division are equal. Because multiplication and division are equal, you work left to right and do whatever operation comes first. Multiplication and division come before addition and subtraction, which also have an equal relationship.
Therefore, if you have simplified the terms inside the parentheses first, and have done the exponents second, then multiplication would come next. So that’s the answer, multiplication.

Answer:
The dimensions of the box are 38.48 x 14.48 x 5.26 in.
Step-by-step explanation:
We will have a piece of cardboard with squares of side x cut from the corners to make a open box.
The volume of the box can be written as:
To calculate the maximum volume, we derive and equal to zero
We apply the quadratic equation to know the roots of the equation
The first solution is physically impossible, as the side that is cut would be bigger than 25.
So the real solution is for x=5.26 in.
Then, the dimensions of the box are:

Define price and weight
--------------------------------------------------------------------------------
Let the price of the diamond be y and the weight be x.
--------------------------------------------------------------------------------
General equation for y varies directly as square root of x
--------------------------------------------------------------------------------
y = kx², where k is a constant
--------------------------------------------------------------------------------
Find the constant k
--------------------------------------------------------------------------------
when x = 12, y = 7200
7200 = k(12)²
7200 = 144k
k = 7200 ÷ 144
k = 50
--------------------------------------------------------------------------------
Substitute k into the equation
--------------------------------------------------------------------------------
y = 50x²
--------------------------------------------------------------------------------
Calculate the weight of the two broken diamonds
--------------------------------------------------------------------------------
The diamond is broken into 3:1
3 + 1 = 4
4 shares = 12
1 share = 12 ÷ 4
1 share = 3 decigrams
3 shares = 3 x 3
3 shares = 9 decigrams
Ratio 1 : 3 = 3 decigrams : 9 decigrams
--------------------------------------------------------------------------------
Find price of the of the 3 decigrams
--------------------------------------------------------------------------------
y = 50(3)²
y = $450
--------------------------------------------------------------------------------
Find the price of the 9 decigrams
--------------------------------------------------------------------------------
y = 50(9)²
y = $4050
--------------------------------------------------------------------------------
Total price of the 3 decigrams and the 9 decigrams
--------------------------------------------------------------------------------
$450 + $4050 = $4500
--------------------------------------------------------------------------------
Lost incurred
--------------------------------------------------------------------------------
$7200 - $4500 = $2700
--------------------------------------------------------------------------------
Answer: The lost incurred is $2700
--------------------------------------------------------------------------------
