Evaluate the expression at specific values of their variables.

Question

Evaluate j2 − 3k + j, when j = 6 and k = 10.

Answer 1

To evaluate the expression j2 − 3k + j when j = 6 and k = 10, we substitute these values of j and k into the expression.

Replacing j with 6 and k with 10, we get:

(6)2 - 3(10) + 6

Simplifying the expression inside the parentheses first, we have:

36 - 3(10) + 6

Multiplying 3 by 10, we get:

36 - 30 + 6

Next, subtracting 30 from 36, we get:

6 + 6

Finally, adding 6 and 6, we get:

12

Therefore, when j = 6 and k = 10, the expression j2 − 3k + j equals 12.
