HELP SOMEONE I need help

Step-by-step explanation:

(a)

To evaluate f(5) substitute x = 5 into f(x), that is

f(5) = 2(5) - 1 = 10 - 1 = 9

(b)

To evaluate g(x - 2) substitute x = x - 2 into g(x), that is

g(x - 2)

= (x - 2)² + x - 2 + 1 ← expand (x - 2)² using FOIL

= x² - 4x + 4 + x - 2 + 1 ← collect like terms

= x² - 3x + 3

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
