There are 12 inches in a foot how many square inches are in 1 1/2 feet

144.

The reason is because 1 ft = 12 in, (1 ft)2 = (12 in)2 = 144 in2.

(3x-8) or (3x+8)

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 %
