x + 4 = 15
- 4 -4
x = 11
You would subtract 4 because you need to isolate the x to get the value of x. You would subtract it to both sides because whatever you do on one side, you have to do it to the other side.
Answer:

Answer:
4√6
Step-by-step explanation:
For right now, I will assume that the "<em>Follow my new brainly at..</em>" part is irrelevant.
Anyways, to find the square root of a number, usually the best way is to find its prime factorization first:
96 : 
We can rewrite that as:
Simplify!
Since is the same thing as 
, that is our answer.
Thusly, as seen above, the answer is 
.
Hope this helps! ((;
If the solution of x is 3, then the solution of 6x would be 18, because 3*6=18. :)
Answer:
<h2>3x³ + 5</h2>
Step-by-step explanation:
( 4x - 2x³ ) + ( 5x³ - 4x + 5)
<u>Remove the parenthesis</u>
That's
4x - 2x³ + 5x³ - 4x + 5
<u>Group like terms</u>
We have
5x³ - 2x³ + 4x - 4x + 5
We have the final answer as
<h3>3x³ + 5</h3>
Hope this helps you
