Question

you are giving an expression for the volume of the rectangular prism. find an expression for the missing dimension

Answer 1

let be the missing side Y
you know that the volume of a rectangular prism is area of base time height
so can you rewriting this knowledge using the missed side ?

Answer 2

area of base so area of a rectangle equal ?

Answer 3

length times wihth

Answer 4

exactly so than you use what you know there note the missed side by one y

Answer 5

ok so x+2 times x+4 times y?

Answer 6

just area of base equal y*(x+4) - yes ?

and the volume will be equal with area of base time the height - yes

Answer 7

ok

Answer 8

so than you can writing

V = y(x+4)(x+2) - exactly how you have wrote above
so for you can calcule the missed side just rewrite this equation for y - ok. ?

Answer 9

k

Answer 10

do i foil it

Answer 11

V=y(x+2)(x+4) divide both sides by (x+2)(x+4) and will get the equation for y

Answer 12

wat

Answer 13

V y(x+2)(x+4)
----------- = ------------ yes ? but in the right part the (x+2)(x+4) from the top and
(x+2)(x+4) (x+2)(x+4) bottom will simplified and will get

V
---------- = y
(x+2)(x+4)

yes ?

Answer 14

ok

Answer 15

do you understand it sure right ?

Answer 16

yes

Answer 17

so than was my pleasure

good luck

bye bye
