The sum of three consecutive even integers is 36. What is the second integers?

podryga [215]

let the consecutive even integers be 2x , 2x + 2 and 2x + 4

let's solve for values of the integers :

$2x + 2x + 2 + 2x + 4 = 36$

$6x + 6 = 36$

$6x = 36 - 6$

$x = \dfrac{30}{6}$

$x = 5$

therefore, the consecutive even integers are :

$2x = 2 \times 5 = 10$

$2x + 2 = 10 + 2 = 12$

$2x + 4 = 10 + 4 = 14$

I hope it helped...

Brainliest, please!

Step-by-step explanation:

sqrt(5) + 2sqrt(16)

sqrt(5) + 2(4)
