Which expression represents the volume, in cubic units, of the composite figure? (52)(13) – (52)(12) (52)(13) – (52)(25) (52)(13) + (52)(12) (52)(13) + (52)(25)

in the given diagram, we have a composite solid made up of two shapes, a cylinder and a cone .

and to find the total volume, we have to find the volume of each solid, and the formula that we have to use here is

and on substituting the values, from the diagram, we will get

adding them , we will get the total volume which is

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
