Answer: 6
Step-by-step explanation:
In any algebraic expression a term could be a variable(a,b,c,...), or a constant (numerical value) or a product of variables and a constant.
For example : In expression \(5x^2-7xy+4c-4\) , there are 4 terms : \(5x^2,\ -7xy,\ 4c\ ,\ -4\)
Let's take one more example : \(3y+2x-7xy^2\)
In this expression there are only 3 terms , that are \(3y,\ 2x,\ -7xy^2\)
The given expression : \(3x^3y + 5xz -4y + x -z + 9\)
There are total 6 variable terms , that are :
\(3x^3y ,\ 5xz,\ -4y ,\ x,\ -z ,\ 9\)
Hence, the correct answer is : 6
