Julio added 6 cubes to his prism. calculate the volume. how has the volume changed? (the picture is without the 6 cubes) will award 100 points

Step-by-step explanation:

Assuming the length of each cube's sides is s, then the volume of each cube is V = s³.  The number of cubes before adding is 2×3×3 = 18.  So the total volume is:

V = 18s³

After adding 6 cubes, the volume becomes:

V = 18s³ + 6s³

V = 24s³

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

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
