What is PEMDAS?
The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.
Given:
We have an expression,
3 × (3 + 12 ÷ 3) - 4.
In order to solve the problem,
we can use PEMDAS.
First, we solve parenthesis,
and division.
3 × (3 + 4) - 4.
Now,
3 × 7 - 4.
Now, multiplication,
21 - 4.
= 17
Therefore, the solution is 17.

Answers
Answer:
1). Option A is correct.
2). option A is correct.
Step-by-step explanation:
1).
Given : Area of Base = 6 ft.² and height, h = 13 ft.
Volume of pyramid =
=
= 2 × 13 = 26 ft.³
Therefore, Option A is correct.
2).
Side of square of base = 6 inches.
Height of pyramid = 12 inches
Base Area = Area of Square
= side × side = 6 × 6 = 36 inches²
Volume of pyramid =
=
= 36 × 4 = 144 inches³
Therefore, Option A is correct.
