Which expression is equal to (x+2)(x-4)/(x-4)(x+4) A) x-2/x+4

B) x+4/x+2

C) x-2/x-4

D) x+2/x+4

The expression equal to is

Option D is correct.

Step-by-step explanation:

We need to solve the expression

Since it is a fraction, and all terms are multiplying with each other we can cancel out common terms.

Since x-4 is both in numerator and denominator so, it will be cancelled out and we will get:

So, the expression equal to is

Option D is correct.

366

step-by-step explanation:

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
