Which of the following expressions is equivalent to 48a^3-75a

3a(16a^2 - 25)

Step-by-step explanation:

48a^3-75a

We can find the factors

48a^3= 2×2×2×2×3×a×a×a

75a= 3×5×5×a

Common factor= 3a

Therefore,

48a^3= 3a(16a^2)

75a= 3a(25)

We then put them back into the question

48a^3-75a= 3a(16a^2 - 25)

step-by-step explanation:

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 %
