since it has a diameter of 28, then its radius must be half that or 14.

Answer:
1.954
so 4 is in the thousandths
Step-by-step explanation:
The answer would be B, because since there are four quarts in a gallon, we take 1 and 1/2 and revert that back to quarts. That gives us 6. The graph clearly shows two, being B.
Answer:
21x - 42, see below :)
Step-by-step explanation:
Hello!
We know that f(x) is equal to 3x - 6
We want to know what 7 * f(x) is so we should first substitute f(x) for 3x - 6
7 * f(x)
7(3x-6)
We use distributive property to open the parenthesis:
7 * 3x + 7 * -6
21x - 42
