Question

Simplify. 18x + 3xy + 5y −2(6xy − 2y + 4) A) 18x − 9xy + 9y − 8 B) 18x + 9xy + 9y − 8 C) 18x + 9xy − 9y + 8 D) 18x − 9xy + y − 8

Answer 1

18x+3xy+5y-2(6xy-2y+4)

18x+3xy+5y-12xy+4y-8

18x-9xy+9y-8

The answer is D

Answer 2

Option A.

Explanation:

The given expression is

`18x+3xy+5y-2(6xy-2y+4)`

We need to find the simplified form of the given expression.

Using distributive property, we get

`18x+3xy+5y-2(6xy)-2(-2y)-2(4)`

`18x+3xy+5y-12xy+4y-8`

Combine like terms.

`18x+(3xy-12xy)+(5y+4y)-8`

`18x-9xy+9y-8`

Therefore, the correct option is A.
