x 4 = 12

Step-by-step explanation:

We know that we are multiplying by 4.

So we just add , 4 times.

+ + + = ?

The first rule is that we do not mess with the denominators. We simply add 3.

3 + 3 + 3 + 3. This equals 6 + 6. Which equals 12.

Our new equation looks like, .

Now simplify.

12 / 4 = 3.

We now know that x 4 = 12.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
