Answer:
j(x) = 36 x - 60
Step-by-step explanation:
Here, the given functions are:
k(x) = 12
and m(x) = 3x - 3
Now, we need to find the expression for j(x) = k(x) * m(x)
By DISTRIBUTIVE PROPERTY:
A(B-C) = AB - AC
[tex]k(x) \times m (x) = 12 \times (3x -5)\\ = 12(3x) - 12 (5)\\= 36x - 60[/tex]
or, k(x) * m(x) = 36x - 60
Hence, j(x) = 36 x - 60
