Show, using a numerical example, that the expressions (x + 2)^2 and x^2 +4 are not equivalent.

Use x = 5.

Step-by-step explanation:  

For x = 5, the two expressions yield these two answers:

1.  (5+2)^2 = 49

2.  5^2 + 9= 25

49 ≠ 25:  The expressions are not equivalent.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
