evaluate 6k - j^2 + 2k divided by l when j = 5, k = 12, and l = 3.
To evaluate the expression, we substitute the given values into the expression.
When j = 5, k = 12, and l = 3, we have:
6k - j^2 + 2k divided by l
= 6(12) - (5)^2 + 2(12) divided by 3
= 72 - 25 + 24 divided by 3
= 71 + 24 divided by 3
= 95 divided by 3
= 31.67
Therefore, 6k - j^2 + 2k divided by l equals 31.67 when j = 5, k = 12, and l = 3.
