Solve 3(k−4)=18.(1 point)

K=10

Step-by-step explanation:

So first distribute

3x-12=18

add 12 on both sides

3x=30

Divide 3 on each side

x=10

10

Step-by-step explanation:

1. 3(k-4)=18

2. 3k-12=18

3. 3k=30

4. k=10

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.
