Evaluate 6k − j^2 + 2k ÷ l when j = 5, k = 12, and l = 3.
To evaluate the expression 6k - j^2 + 2k ÷ l when j = 5, k = 12, and l = 3, we substitute the given values into the expression:
6k - j^2 + 2k ÷ l
= 6(12) - (5)^2 + 2(12) ÷ 3
= 72 - 25 + 24 ÷ 3
= 72 - 25 + 8
= 47 + 8
= 55
Therefore, when j = 5, k = 12, and l = 3, the value of the expression 6k - j^2 + 2k ÷ l is 55.
