How Do I Simplify 8R - 4(2R +1) + 4?

8

Step-by-step explanation:

8r - 4(2r + 1) + 4

First, you have to use the distributive property to solve what's inside the parenthesees:

4(2r) + 4(1) = 8r + 4

Now, the problem is:

8r - 8r + 4 + 4

When we subtract 8r - 8r, we get 0. Therefore the variable r is gone since the coefficient is 0.

The problem now is:

4 + 4

We get the answer of 8.

Sorry if this explanation is bad, but i hope this helps!

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
