MAY i ASK where is the picture my good kind sir?
The answer that I got is 3
The answer is c (x+21) and (x-2) you have to find two numbers that multiply yo give you -42 and add to give you 19
The answer is 256pi if you have a calculator, and it says to put it in 3.14 for pi, do the same steps I show here, but instead of pi, you would put 3.14. But I hope this helps you
