Answer 2

Answer:

Here, in expression, $8z+4$, the co-efficient of $z$ is $8$.

Step-by-step explanation:

Given : The expression is $8z+4$.

To find : The co-efficient of $z$.

Solution :

• The given expression is $8z+4$.
• We have to find the co-efficient of $z$.
• Co-efficient is the number associated with a variable in an expression.

      Ex. Consider an expression, $3x^{2} -2x+5$. The co-efficient of $x$ is $-2$ while co-efficient of $x^{2}$ is $3$.

• Here, in expression, $8z+4$, the co-efficient of $z$ is $8$.
