Question

Simplify 7(x + 3). 7x + 3 7x + 21 7x + 10 x + 2

Answer 1

7x +21


7 x X = 7x
7 x 3 = 21

Answer 2

The correct option is 2.

Explanation:

The given expression is

`7(x+3)`

Distributive property: If a,b and c are three real values, then

`a(b+c)=ab+ac`

In the given expression a=7, b=x and c=3.

Using distributive property, the given expression can be written as

`7(x+3)=7(x)+7(3)`

`7(x+3)=7x+21`

The simplified form of given expression is 7x+21. Therefore the correct option is 2.
