Answer:

Jenny's room

Step-by-step explanation:

The area formula is:

area=length*width

Jenny:

a=l*w

a=13*12

a=156 feet^2

Ruth:

a=l*w

a=14*11

a=154 feet^2

So, Jenny's room has the greater area, because 156 is greater than 154

Hope this helps!

Well, to get perimeter, you add the length and width, and then multiply your answer by two. So:

Jerry-

13+12=25

25*2=50

Ruth-

14+11=25

25*2=50

So both rooms are equal.

Hope this helps!!

I'm assuming you're looking to find the expanded form of the number?

This number is in scientific notation. The easiest way to convert it to a normal number is to move the decimal place 14 to the right. I've attached a picture showing how to do this. You should get 630,000,000,000,000

There's a faster way to do this - notice that you need to move the decimal 14 to the right, and there's one number already after the decimal place. Therefore, 13 places will be filled with zeros. So, just write out 63 and add 13 zeros.

For more general help on scientific notation, check out these videos: https://www.khanacademy.org/math/pre-algebra/pre-algebra-exponents-radicals/pre-algebra-scientific-notation/v/scientific-notation-old

Hope that helps! Feel free to message me or leave a comment if I can clarify anything :)

-3 + (-8)<br> how can i do this
murzikaleks [220]

Answer: -11

Step-by-step explanation:

+(-8) can be simplified to -8 because when you multiply a positive sign by a negative sign, the outcome is a negative sign. So your problem is -3-8= and the answer is -11 because when two numbers with the same sign are subtracted/added by each other, the numbers just get added and the sign stays the same. If you're still confused, use a number line. Hope this helps!
