Answer:

-543

Step-by-step explanation:

For every value of k, you substitute 9 and for every value of c, you substitute 2

-6((8x(9)+ 9(2)) - 3

so order of operations says you should do what's in the parentheses first.

8 x 9= 72     and 9 x 2 = 18

so now you have -6 ( 72 + 18) -3

Finish the calculating inside the parentheses:   -6 (90) -3

and now multiply -6   and 90 before you subtract 3

-6 x 90 = -540

-540 - 3   = -543
