Question

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

Answer 1

Answer:

The correct option is 2.

Step-by-step 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.

Answer 2

7x +21


7 x X = 7x
7 x 3 = 21
