To evaluate the expression, we substitute the given values of j, k, and l into the expression:
And how do you do that? I'm confused.
To substitute the given values of j, k, and l into the expression 6k − j2 + 2k ÷ l, replace j with 5, k with 12, and l with 3.
So the expression becomes:
6(12) - (5)^2 + 2(12) ÷ 3
Now we simplify each part of the expression:
6(12) = 72
(5)^2 = 25
2(12) = 24
Finally, we evaluate the expression:
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 − j2 + 2k ÷ l is 55.
So the expression becomes:
6(12) - (5)^2 + 2(12) ÷ 3
Now we simplify each part of the expression:
6(12) = 72
(5)^2 = 25
2(12) = 24
Finally, we evaluate the expression:
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 − j2 + 2k ÷ l is 55.
