Simplify the expression by combining like terms, if possible. If not possible, select “already simplified.” .4a^2+2a+4a^2-5 A. already simplified B. 4a^2+2a-5 C. 8a^2+2a-5 D. -8a^2-2a+5 help plz

help?

OpenStudy (debbieg):

Do you know what "like terms" are, and how to combine them?

OpenStudy (anonymous):

yes

OpenStudy (debbieg):

"like terms" are terms where the variable part looks the same - only the coefficients are (possibly) different. So the variable(s), and the powers, are identical. E.g.: \(\large z^2+5z^2\) ARE like terms: both have \(\large z^2\) as the only variable part, so they combine by adding the coefficients: \(\large z^2+5z^2=6z^2\)

OpenStudy (debbieg):

OK, well, then what are you stuck on? If you understand how to identify like terms, and how to combine them, that's really all you need for this problem. What answer do you get?

OpenStudy (anonymous):

C.

OpenStudy (debbieg):

That is correct. :)

YEA!

im smart wow

OpenStudy (debbieg):

lol indeed! :) nice job!

OpenStudy (anonymous):

YEA!

Use the distributive property to simplify the expression. -7(8x-3)+x

OpenStudy (anonymous):
