Use PEMDAS method to execute operations in the following order:
- Parentheses
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
First equation:
12 + (38 - 18)2 = 12 + 20 × 2 = 52
Second equation:
(12)2 - 6(2 - 23) = 24 - 6(-21) = 24 + 126 = 150
Hope this helps.

Step-by-step explanation:
Answer: The volume is the product of the Length, Width, and Height: V = LWH.
Step-by-step explanation: We are given V = 240 in.3, and H = 6 in., and L = W + 3 in.
Thus 240 in.3 = (W+3 in.)*W*(6 in.) so W(W+3 in.) = 240 in.3 / 6 in. = 40 in.2
Using the distributive property and moving the constant to the left gives:
W2 + (3 in.)W - 40 in.2 = 0
This factors:
(W + 8 in.)(W - 5 in.) = 0
The first factor gives W = -8 in. which is nonsense because it is negative.
The second factor gives a valid answer of W = 5 in.
