Question

j^2 - 3k + j, when j = 6 and k = 10.

Answer 1

To evaluate the expression j^2 - 3k + j, when j = 6 and k = 10, we substitute these values into the expression and perform the calculations.

First, substitute j = 6 and k = 10 into the expression:

(6)^2 - 3(10) + 6

Next, we simplify the expression using the order of operations (PEMDAS/BODMAS):

36 - 30 + 6

Now, perform the addition and subtraction:

6 + 6

Finally, perform the addition:

12

Therefore, when j = 6 and k = 10, the expression j^2 - 3k + j equals 12.
