Answer:
x = -1 or x = -7
Step-by-step explanation:
y = (x + 4)^2 - 9
To find x-intercept, set y = 0
=> (x + 4)^2 - 9 = 0
=> ( x + 1)( x + 7) = 0
=> x = -1 or x = -7
I don't really know what the question was, but I am guessing that it is 20% times 45. The answer I got was 9. I hope this helps, sorry if not. c;
