Rewrite the expression by using grouping symbols

Elan Coil [88]

Answer:

D) $y(5+a)$

Step-by-step explanation:

Given expression:

$y\times5+y\times a$

The above expression can be rewritten using grouping symbols by using properties of equality.

We apply distributive property of multiplication according to which:

$ab+cb=b(a+c)$

the product of a number and each addend individually added together is equal to the product of that number and sum of the addends.

So, we can write

$y\times5+y\times a=y(5+a)$
