How many variable terms are in the expression 3x3y + 5xz − 4y + x − z + 9?

more detail

step-by-step explanation:

answer is because 4×10=40

and 98×4= is 392

40,392

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
