Question

Rewrite the expression without using grouping symbols: y • 4 + y • z

Answer 1

Answer:

y(4 + z)

Step-by-step explanation:

Here in this problem, we have to rewrite the expression y • 4 + y • z without using the grouping symbols.

Now, we can assume that '•' symbol here represents the multiplication symbol.

So, there are two parts of the expression and in both of the parts, y is multiplied. Hence, we can take common y from both parts.

So. y • 4 + y • z = y(4 + z).  

Therefore, option c matches the result. (Answer)
