The answer is 1 if you do 2 x .5 you get 1.
1800
20%=1/5 which means 360x5 is the number of people at the concert
360x5=1800
hope this helps :)
Answer: F
Explanation: the angles add up to 180 degrees (on a straight line)
(x^2+7x+1)/(x^2+2x-15)
A discontinuity, specifically a vertical asymptote, will occur when the denominator is equal to zero as division by zero is undefined.
(x^2+2x-15)
(x+5)(x-3)
So you will have two of them, when x=-5 and x=3
