If the factors of a polynomial are x+8 and x+4, what values of x make of polynomial 0?

  x = -8, x = -4

Step-by-step explanation:

Adding a number and its opposite gives a result of 0. That is, x+8 will be 0 when x = -8, because -8 +8 = 0.

Likewise, x+4 will be zero when x = -4, because -4 +4 = 0.

The values of x that make (x+8)(x+4) = 0 are -8 and -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 %
