Best ResponseYou've already chosen the best response.1`The width of a rectangle is 8 cm less than its length` if the length is L, then what is the width in terms of L?

Best ResponseYou've already chosen the best response.1now we use the perimeter of a rectangle formula P = 2L + 2W

Best ResponseYou've already chosen the best response.1replace P with 52 replace W with L8 doing this gives 52 = 2L + 2(L8) now solve for L

Best ResponseYou've already chosen the best response.0l'm sorry but what would be L. Like the number I really don't understand

Best ResponseYou've already chosen the best response.1L stands for the length it's unknown at this point, but when you solve for L, you figure out what the number for the length is

Best ResponseYou've already chosen the best response.1example: if 2L = 10, then L = 5

Best ResponseYou've already chosen the best response.1what would 2(L8) turn into?

Best ResponseYou've already chosen the best response.1so 52 = 2L + 2(L8) turns into 52 = 2L + 2L16

Best ResponseYou've already chosen the best response.1then you combine the 2L terms 2L+2L = 4L making 52 = 2L + 2L16 turn into 52 = 4L16

Best ResponseYou've already chosen the best response.1since L = 17, the width is W = L8 = 178 = 9
