-2[9 - (x + 7)]

OpenStudy (anonymous):

This is easy and you really can't figure it out?

OpenStudy (anonymous):

no..

OpenStudy (anonymous):

Well first off do you know your order of operations?

OpenStudy (anonymous):

PEMDAS, right?

OpenStudy (anonymous):

Yes, good. All you have to do is follow them. You know how to do that right?

OpenStudy (anonymous):

Yeah, but the bracketts are confusing.

OpenStudy (anonymous):

I think of brackets like fancy ( ). Just start with the (x+7).

OpenStudy (anonymous):

Do you need any more help?

OpenStudy (anonymous):

yeah, I have another question

OpenStudy (anonymous):

Fire away!

OpenStudy (anonymous):

4n 5 + 3.5n 5 + (-2.1n 5).

OpenStudy (anonymous):

Is there any more signs in the equation. What you typed doesn't make much since.

OpenStudy (anonymous):

the fives are exponents

OpenStudy (anonymous):

sorry

OpenStudy (anonymous):

Ok that makes more since. Give me a minute to solve.

OpenStudy (anonymous):

Ok, this one is a little more tricky. Do you have your answer?

OpenStudy (anonymous):

Yeah, I just guessed. Thank you though.

OpenStudy (anonymous):

WAIT!! Please try to solve the problem or atleast send me your guess!

OpenStudy (anonymous):

okay!

OpenStudy (anonymous):

Thank you.

OpenStudy (anonymous):

5.4n to the 5th power.

OpenStudy (anonymous):

You know how to multiply using a power right?

OpenStudy (anonymous):

yeah, but I just took like terms.

OpenStudy (anonymous):

Ok but the problem once your done multiplying you add it all to into one answer. If you had 2^2+9(x+3^2) you would solve it the same way.

OpenStudy (anonymous):
