PLEASE HELP 20 POINTS Stephen and Chelsea want to increase the volume of this prism by 72 cubic centimeters. Chelsea wants to add eight layers, and Stephen says they only need to add four layers. Their teacher tells them they are both correct. Explain how this is possible.

Step-by-step explanation:

2.

- the volume of initial prism is 3*3*6=54 cm³;

- the number of cubics of the requested 72 cm³ is 72;

- 'Chelsea wants to add eight layers' means 72=3*3*8 cubics, then one layer in this case consists of 3x3 cubics;

- 'Stephen says they only need to add four layers' means 72=4*3*6 cubics, then one layer in this case consists of 3x6 cubics.

3.

- the volume of initial prism is 4*4*1=16 in³; it means one layer is 16 inches³;

- according to the requirement 3 layers is 16*3=48 in³; three times 16.

- according to the requirement 5 layers is 16*5=80 in³; five times 16.

- according to the requirement 7 layers is 16*7=112 in³; seven times 16.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

answer: idk
