I’m having a hard time with answering these type of questions for some reason.

3 : 21 3/4

Because it is a enlargement of 3, you need to multiply each side by 3 times.

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
