Denise is checking to determine if the expressions x+x+6 and 4+3x-2 are equivalent. When x=4, she correctly found that both expr

essions have a value of 14.
When x=2, she correctly evaluated the first expression to find that x+x+6=10. What is the value of the second expression when x=2, and are the two expressions equivalent?

Answer:

Value of the second expression when x=2 is:

8

and the two expressions are not equivalent

Step-by-step explanation:

Value of the expression 4+3x-2 at x=2 is:

=4+3×2-2

=4+6-2

=8

Hence, value of the second expression when x=2 is:

8

Hence, two expressions are not equivalent

(since, their value at x=2 is different)
