Use these expressions to answer the questions.
Expression A: (x + y)
Expression B: (x) + (y)
Choose a positive value for x and positive value for y. Then, do the following steps:
Substitute the x- and y- values into expression A and expression B.
Simplify.
Write the result of each expression. Repeat these steps for the next three situations: Choose a negative value of x and a negative value y. Choose a positive value of x and a negative value of y. Choose a negative value of x and a positive value of y. 2.
Describe any patterns you notice. Are the two expressions ever equal? Can one be greater than the other?

Respuesta :

Answer:

Both expressions are equal. One expression cannot be greater than the others.

Step-by-step explanation:

The given expressions are:

A:   (x + y)

B:   (x) + (y)

Let x = a and y = b

A:   (a+b) = a+b

B:   (a)+(b) = a+b

Let x = -a and y = -b

A:   (-a+ (-b)) = -a-b

B:   (-a)+(-b) = -a-b

Let x = a and y = -b

A:   (a+(-b)) = a-b

B:   (a)+(-b) = a-b

Let x = -a and y = b

A:   ((-a)+b) = -a+b

B:   (-a)+(b) = -a+b

We can see the pattern that both expressions are always equal to each other, no matter what value of x and y you plug in. One expression cannot be greater than the other
