I guess his problem is to attach  the thing not capturing it.
See, thenewkid, when you click on "reply" in the bottom of the page, the window opens
now under the area given to type, oon the left there is an option "additional options..."
click on that and then attach

vol = 216 times

k= cube root [ 216]
k = 6

k = r/3
6 x 3 = r
r = 18

same way for height .. h = 6 x 7 = 42

remember always .. for vol k is k³ and area k²

s08qp2q10
(ratio of sides)³ = ratio of volumes
ratio of volumes is 1:216
so ratio of sides should be cube root of 1:216
ratio of sides= 1:6
to get lengths, multiply by 6
r=3x6=18cm
h=7x6=42cm
hope that helps!
(sorry VIN, didn't realise you answered already)

any ways  tk the invariant line as x=-1. the corner (-4,3) moves 4 spaces to the right along the invariant line and it is 3 spaces above the line.

i think this is correct bcause  we had gotten a similar question in our schl exams and the teacher had told us this
