Question 270919: the lenght of a book cover is 1cm more than twice its widht if its widht is x cm and its perimeter is 92 cm, form an equation useing x to repesent the adove Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! : the length of a book cover is 1cm more than twice its width if its width is x cm and its perimeter is 92 cm, form an equation using x to represent the above.
:
L = 2x+1
therefore
p = 2(2x+1) + 2x
:
2(2x+1) + 2x = 92
4x + 2 + 2x = 92
6x = 92 - 2
x =
x = 15 cm is the width
then
2(15) + 1 = 31 cm is the length

:
Check
2(31) + 2(15) = 92
