Which pair of expressions is equivalent? A 4k + 2c and 2(4k + c)
B O 6(3s + 7) and 9s + 13
D 42 +212 and 7(6 + 3z)
F 2(b + 3c) + 5 and 2b + 6c + 10

c

Step-by-step explanation:

a = 6kc and 8kc

b = 60s and 22s

c = 63z and 63z

d = 6bc and 18bc

the image of (6, 9) under a dilation is (4, 6). the scale factor is

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
