What is an equivalent expression to 12a+6b

3(4a + 2b)

Step-by-step explanation:

if we were to expand this back out then we would get 12a + 6b

3 x 4 = 12 then add the a (12a)

3 x 2 = 6 then add the b (6b)

then your plus sign and you have your original ancwer meaning that this problem is correct

the answer is 24

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
