f-1(x)= cube root of 19x squared/x

step-by-step explanation:

the perimeter is increased by a factor of 2

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
