evaluating formulas

[vinceman]

given the formula P=2l+2w, find the width w of a rectangle when its perimeter p is 17.6 units and its length l is 3.3 units.
I need all work please and the answer.

would be better to show what you have done so far......

P=2l+2w

in this formula place P =17.6 and l=3.3

17.6 = 2(3.3) +2w

now multiply the 2(3.3) and then move it to the left side(becomes negative)
With this new value divide it by 2 to get the "w" by itself.

to continue....


17.6 = 2(3.3) +2w

17.6 = 6.6 + 2w

17.6-6.6 = 2w

11 = 2w

11/2 = w

over to you

After your poll and now this, what's the point? Unless you go through a serious attitude adjustment, you will not gain any value, anywhere, froim your queries.

You show us your work.

You get to work and figure it out and you will feel better about it.
