Eight less than four times the sum of a number and three is sixteen

4(x+3) - 8 = 16        (this is the equation)

step by step:

4x + 12 - 8 = 16

4x + 4 = 16

4x = 16 - 4

4x = 12

x = 12/4

x = 3

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.
