Which of the following is an example of an identity? (1) x²+2x+8 =(x + 2)(x+4)

(2) 2x(x-3)+5x-15 = (2x+5)(x-3)

(3) x² +9=(x+3)

(4) x' +8=(x+2)(x²+4)

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 %
