Afriend rewrote the expression 5(x+2)as 5x+2. wrote a few sentences to your friend explaining the error. then, rewrite the expression 5(x+2)

5x+2

Step-by-step explanation:

Ok so the expression 5(x+2) is not 5x+2 because you have to use the distributive property. So with that being said:

5(x+2)=5 times x and 5 times 2

so the realest answer is 5x+10 instead of 5x+2

EXPLANATION: The error in the rewritten expression done by your 'friend' is that he/she did not multiply the five in the parenthesis by ALL terms (meaning numbers and/or variables) as he/she should have done according to the distributive property. In the distributive property, you distribute equally to all numbers and parts in the equation or expression.

Take, For example, 7(x+4). Instead of just multiplying 7 times x in the parenthesis, you would also multiply seven times to four and add that to the end of the expression, making the rewritten expression 7x+28.

So, the correct rewritten expression for this problem is 5x+10.

final answer is : )
