Amy and stephanie were playing a number game. amy picked a number and told stephanie that if she added 9 to the number and multiplied the sum by 3, it would equal 12. which equation could stephanie use to find the number, x?
a.
3(x) + 9 = 12

b.
3(x + 9) = 12

c.
3 + (x + 9) = 12

d.
9(x + 3) = 12

dont think so

step-by-step explanation:

where are the graphs?

step-by-step explanation:

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 !
