Medal for Help :) What is the simplified Form of the expression 5(14-2)2 --------- 2 A.60 B.30 C.72 D.360

OpenStudy (anonymous):

Multiply 2 by everything.

OpenStudy (anonymous):

b

OpenStudy (anonymous):

Wait, I think I'm wrong.

OpenStudy (anonymous):

Ok, so the first thing you want to do is to multiply all the things that need to be multiplied. Once you've done that, divide the whole thing by 2 (at least, I think that's a fraction bar there). What do you get?

OpenStudy (anonymous):

B, is wrong. Show me what you did.

OpenStudy (anonymous):

Me?

OpenStudy (anonymous):

Hey @gaberdeen! It's great to see you again lol. I was talking to @JuniorEinstein1

OpenStudy (anonymous):

Oh! Whoops xD

OpenStudy (anonymous):

I am lost

OpenStudy (anonymous):

Ok, so try adding the numbers in the parentheses together first. Then, multiply that number by the other numbers next to it. What do you get?

OpenStudy (anonymous):

\[\frac{ \left( 5(14-2) \right) }{ 2}\]

OpenStudy (anonymous):

Oops, forgot the ^2*

OpenStudy (anonymous):

16

OpenStudy (anonymous):

160

OpenStudy (anonymous):

Oooh, is the number to the right of the parentheses an exponent?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

In other words, distribute the parenthesis first. Once you got that answer, use that answer to divide by 2.

OpenStudy (anonymous):

Yes, add the numbers in the parentheses, multiply by five, then raise the power of the resulting number by two. Then divide by two. What do you get?

OpenStudy (anonymous):

Fell offline

OpenStudy (anonymous):

@JuniorEinstein1 We told you how to set it up already. First, solve the parenthesis then divide that number by 2.

OpenStudy (anonymous):
