Expand the brackets and simplify.

(0.5)(6x – 2) – 3(x – 1)

2

Step-by-step explanation:

(0.5)(6x-2)-3(x-1) = (3x-1)-(3x-3)

                           = 3x-1-3x+3

                           = 2

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d
