Well when you simplify it you get this,

0=-24,


Do what’s inside the parentheses first

3-3 is 0, 3•0 is 0

2•positive 3 is 6

6- -30 is -24

So you have 0=-24

Or just -24 :)

12n^3 + 16n^3 can someone please help me with this?
vodka [1.7K]

Answer:

4n^{3} (3n^{2} + 4)

Step-by-step explanation:

Assuming the problem is asking you to factor out the formula, it can be done easily by finding a common number with the two givens.

4 goes into both 12 and 16 evenly, so we will use this to factor. But that's not all, we have the n-variable to worry about.

Look at the n-variable exponents in the problem, take the highest power that can go be subtracted from both and use that. We have a n^{5} and n^{3}. Since 5 can't go into 3, we must use 3 to factor.

Our factoring variable will therefore be 4n^{3}. Now, use this to simply divide and get the answer:

( 12n^{5} + 16n^{3} ) / 4n^{3}  = 4n^{3}(3n^{2} + 4)

So how did we get this? For the whole numbers, we have to divide: (12/4, 16/4). Next, we have to minus the exponents since we are dividing.

When dividing the 12 and 4, minus the n^{5} and n^{3} to get n^{2}. Get rid of the n^{3} term for the 16 and leave the 4. And there's your answer!

Two angles are supplementary (add up to 180 degrees). The measure of one angle is ten more than the other. Find the measure of e
Aleonysh [2.5K]

Answer:

85° and 95°

Step-by-step explanation:

So, one angle is x, the other angle is x + 10. Using this, you can form an equation.

x + x + 10 = 180

Now, solve the equation.

2x + 10 = 180

2x = 170

x = 85

So, one angle is 85 while the other angle is 95.

85 + 95 = 180,

so we know that our answer is correct.

please help me out! this is urgent please do it correctly heres 10 points and a brainleist if you answer it right
Ber [7]
Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.
