Select the rational expression that is equivalent to the given expression below. 4 / x - 3 a.) x + 2 / x - 3 ÷ 4 / x + 2 b.) x + 2 / x - 3 · 4 / x + 2 c.) x + 2 / x - 3 - 4 / x + 2 d.) x + 2 / x - 3 + 4 / x + 2

For this case we have the following expression:

We must multiply the expression given by the same factor in the numerator and the denominator.

We have then:

Then, rewriting the given expression we have:

The rational expression that is equivalent to the given expression is:

Option B

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
