So triangles bcd and aec are similar. so this makes lines ac and bc similar and lines db and ae similar.
to solve this problem, we just need to do some algebra

now we substitute those values in

which results in

then multiply both sides by 12

soon you should get x=2 with the length of ae being 16
Answer:
k > 100
Step-by-step explanation:
y= x²+20x+k
if the graph doesn't intersect the x-axis it means it has no real roots so the discriminat has to be negative so will have imaginary roots
discriminant is
b²-4ac = 20²-4*1*k = 400-4k for this to be negative k has to be more then 100 so will have 400 - a number bigger then 400
k > 100 is the solution
