: 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
