Write as an algebric expression:

1. half of a number
2. twice a number

0.5x

2x

wrong, n divided by 2and 2 multiplied by n

Check out the difference(?) between

10/2 and 0.5 * 10 and 1/2 of 10
or
24/2 and 0.5 * 24 and 1/2 of 24

Aren't they the same? Don't they all get the same answers?

2 * n = 2n

the book wants you to write an algebric expression for half of a Number so that is N/2 and twice a Number which is N^2

Can you help me with the one below this one in my name

Oops -- twice a number is NOT the same as N squared.

5 * 2 = 10
5^2 = 25

I suggest you study your book more thoroughly.

I don't remember how to factor those problems.

Can you have someone who knows help me please?

They already have. :-)

Thank You.
