Question

Rewrite the expression by using grouping symbols

y . 5 + y . a

A) 5(y+a)
B) a(y .5)
C) y.(5 + y) . a
D) y(5 +a)

Answer 1

D)
`y(5+a)`

Explanation:

Given expression:

`y*5+y* 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*5+y* a=y(5+a)`
