Answer:
A. -3(5x - 13)
Step-by-step explanation:
When you open the bracket
You have -3 x 5x -3(-13)
Negative negative gives you positive
Then it becomes
-15x + 39
12.5 x 2 (you need the diameter to find pi) =25pi ft
The answer is :
-4.472135...
The sign of the product would be the postitive sign because all three integers have the same sign.
