You do 7 times 2 in parentheses and then minus that by 6-4 in parentheses so it will look like this , (7times2) - (6-4) = 12
It is equivalent because of the distributive property. If you multiply 4 by x and y, you get 4x and 4y.
4x + 4y = 4x + 4y
I think the answer is 297.
Explanation:
Replace every x in k(x) with 9
2(9)^2-3(9)
18^2-27
324-27
297
K(9)=297
