Answer:

44

Step-by-step explanation:

k=2: 2*2²-4 = 4

k=3: 2*3²-4 = 14

k=4: 2*4²-4 = 28

-2 + 4 + 14 + 28 = 44

12 divided by 4y+6 = 2/7
Mila [183]

Answer:

The correct answer is y = 9

Step-by-step explanation:

It is given that,

12/(4y + 6) = 2/7

<u>To find the value of y</u>

12/(4y + 6) = 2/7

By cross multiplying,

12 * 7 = 2  * (4y + 6 )

84 = 8y + 12

8y + 12 = 84

8y = 84 - 12

8y = 72

y = 72/8 = 9

y = 9

Therefore by solving the given expression we get the value of y = 9
