Arectangle has a length of 18 cm and a perimeter of 68 cm.
which equation could be used to find the width of the rectangle?
a. w + 18 = 68
b. 18w = 68
c. 2w + 18 = 68
d. 2w + 36 = 68

Well perimeter can be found with the equation P = 2w + 2l where p is perimeter, l is length and w is width. Substitute 18 in for l and 68 for p:
2w + 2(18) = 68
D. 2w + 36 = 68 is the equation.

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
