Answer:
wouldn't that be 81 but i dont know
Answer:
It would be Town B.
Step-by-step explanation:
be So if we have 2/5 out of 100 then we would multiply 5 times whatever number, which would be 20, and then we would multiply the numeratoar times 20 and we would get 40/100 and that would equal -3.40 so then -3.40 is a lower temp that -3.33 so it would be Town B.
The answer is 0! Hope this helps!!! :)
If a factor is x+4, that means that the coefficient of x^2 (the number in front of it, which would be 1) and that 20 should be divisible by 20. Now, if you divide 20 by 4, you would get 5, and 1/1 = 1. So, the 2 factors you have is
(x+4)(x+5)
When you FOIL, you would get
x^2+9x+20, which means
b=9
