how do i set this one up ? 
408-11(2)+

anonymous · Answer

We know that l=4h-11, where l is the length and h is the height.
Then 408 = 2l+2h so 408 = 8h -22+2h. Rearranging gives h=43.

In order for you to put down new sod in the front yard you will need 5400 pieces of sod. Each sod piece is cut into one foot squares. If your yard is 60ft wide , how long is the yard.?

anonymous · Answer

The area is 5400 and the width is 60. So the length is 5400/60 since Area = Length x Width.
