Explain how to solve this equation for x: 456=x²+26x

(x-12) (x+38)

Step-by-step explanation:

Subtract 456 to the other side:

1) x²+26x-456

Factor:

2)      (x-12) (x+38)

Hope this helps again!! :D

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
