An engineer is redesigning a set of cases for computer equipment. One is a cube with side lengths of Xinches, and the other is a rectangular prism whose size is dependent on the size of the cube.
The volume of the prism is modeled by function v.
v(x) = 13 - 12:2+35x

hirap saket sa ulo gahahaha

eve and marks ratios are equivalent

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
