​

Answer 1

the answer is, 3k+5k ;20+6

=8k/26

=3.45454

Answer 2

Answer:

k = 1

Step-by-step explanation:

Given

3: (k + 2) :: 5: (k + 4)

We know that

if a = 3, b = k + 2, c = 5 and d = k + 4 and

a: b:: c: d then

Product of extremes = product of means

⇒ad = bc

⇒3*(k + 4) = 5*(k + 2)

⇒3k + 12 = 5k + 10

⇒5k - 3k = 12 - 10

⇒2k = 2

∴ k = 1
