Solve for x. 9x=3x−36 a) −6 b) −4 c) 4 d) 6

9x = 3x-36

-3x   -3x

6x = -36 Divide both sides by 6

x = -6

hi,

3. 12.15, you are correct.

4.2.01, your first digit is correct,

hope this !

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
