2(x + 14) = 40 Can you please do all the steps of solving this?

Ex:
8(7+1)3=192

8 x (7+1) x 3
8
8x8=64
64x3=192
total=192

6

Step-by-step explanation:

2(x+14)=40

2x+28=40

2x=40-28

2x=12

x=6

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.

i believe the answer is the polygon, heptagon.
