What is the first step for solving this problem: 12÷ 6(3)+8

Division.

Step-by-step explanation:

There are two rules that you follow. One is PEMDAS, and the other is the     left -> right rule.

Note that PEMDAS =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

The order of operation is: P , (E & R) , (M & D) , (A & S), parenthesis meaning they can be interchangeable, due to the left -> right rule.

Solve:

First, divide:

12/6 = 2

Next, multiply:

2 x 3 = 6

Finally, add:

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
