The coordinates of trapezoid EFGH are E(4, 6), F(2, 3), G(4, 2), and H(8, 4). If the image is dilated to E’F’G’H’ and G’ is (8,4
NNADVOKAT [17]
G=(4,2), G'=(8,4)
G'/G=((8/4),(4/2))
G'/G=2
The dilation scale factor is 2, so all lengths will be doubled.
Original distance from G to H: ((8-4)^2+(4-2)^2)^(1/2)
=(4^2+2^2)^(1/2)
=(20)^(1/2)
New distance=2((20)^(1/2))
Original x distance=G+4
Original y distance=G+2
New x distance=G'+8
New y distance=G'+4
x=8+8
y=4+4
H'=(16,8)

Daniel [21]

Answer: divide by 6?

Step-by-step explanation:

What is the least positive integer by which 24 should be divided so that the resulting integer is a perfect square?

If we actually guess and check by dividing by 1, then 2, then 3, then etc. we will get the answer. I tried and divided by 6, which is 4, which is a perfect square. Do not trust me completely on this, for I am not quite sure.
