Question

the perimeter of a retangular sign is not to exceed 50ft. the length is to be twice the width. what widths will meet these conditions?

Answer 1

do you know the formula for the perimeter?

Answer 2

....?

Answer 3

doesnt sy that is all the question that it gives

Answer 4

but yoy should know that P=2l+2w

Answer 5

i havent been in class long and dont know anything about algebra lol

Answer 6

im 35 trying to go back to school

Answer 7

ok:)
if l is the length of the rectangle
w is its width
then P=2l+2w
the length is twice the width=>l=2w
then the perimeter becomes:P=2(2w)+2w=6w
i hope you're following so far?

Answer 8

yes i am thanks

Answer 9

ok,it says the perimeter is not to exceed 50
which means P<=50 ( less than or equal to)
=>6w<=50
=>w<=50/6
w<=25/3
this means all widths which are less than or equal to 25/3 ft are accepted
