how do i solve B) though?

Okay. I think I get it. Thanks for the help.

Thank you so very much

Hi Steve! So with your explanation, am I correct in saying that the error in the above given is (a - b)^2 = (b - a)^2?

Thank you so much Reiny. I clearly understood it.

Thank you very much. I got it now.

Why is it 3 and 4?

Are my answers right or wrong?

Is 2. A and 5. C?

Please respond.

Okay thanks so I’m guessing 2. D? and 3. B?

I’m also on it too weird lol

Ms.Sue no but I’m on it too

Ugh! I got 3/5 and my origional answers were RIGHT. I only trust bobpursley, Ms. Sue, and writeteacher from now on.

whats the answer??!!

liquids or medicines may be measured in kiloliters, hectoliters, decaliters, liters, deciliters, and centiliters. As for millimeters, they may measure pencils or small objects.
