Answer:
6x + 12y
Step-by-step explanation:
Using distributive property means multiplying the number outside of the parentheses to each individual number within the parentheses:
3 × 2x = 6x
3 × 4y = 12y
Since there is an addition sign within the parentheses, we add these two numbers together. However, they are not like terms so their sum cannot actually be calculated
6x + 12y
Result: <u>Circumference = 150.72cm</u>
Explanation:
To find the circumference, C, we will use this formula:
C = 2 * 3.14 * r
Substitute:
C = 2 * 3.14 * 12
Multiply:
2 x 12 = 24
24 x 3.14 = 75.36
___________________________________________________________
And since the question asked for two revolutions.
All we need to do is multiply 75.36 by 2:
75.36 x 2 = <u>150.72</u>
The answer to you r question is 975. I hope this helps you
