Question

9(k+12)+4k2 when k= 3 the 2 is small

Answer 1

171

Explanation:

When you say "the 2 is small" I think you mean it's an exponent so the equation would look like....

`9(k+12) + 4k^(2)`

if k=3 we would replace all the k's with 3.

9(3+12) + 4(3)²

9(15) + 4(9)

135 + 36

171

So the answer would be 171

Hope that helps and have a great day!
