whats w stand for? -7w + 3(w+2)= -14
509w
Perimeter = length + length + width + width Let "w" = width, then "7w" must equal the length (because it's 7 times the width) 7w + 7w + w + w = perimeter 16w = perimeter
In ( w ) weeks, there are ( 7w ) days since each week has 7 days. Adding the ( w ) additional days gives a total of ( 7w + w = 8w ) days. Therefore, in ( w ) weeks and ( w ) days, there are ( 8w ) days.

Ill assume you mean for an are of a rectangle. w will stand for width. So you know the equation for a rectangle is L*W, so if length is 7W, then the area is 7W*W=Area or 7W^2
As a term of an expression in math, 72w means 7 times w
509w
7w=122 122/7= 17.43 w=17.43
7w - 4w - 6w = (7 - 4 - 6)w = -3w
Perimeter = length + length + width + width Let "w" = width, then "7w" must equal the length (because it's 7 times the width) 7w + 7w + w + w = perimeter 16w = perimeter
In ( w ) weeks, there are ( 7w ) days since each week has 7 days. Adding the ( w ) additional days gives a total of ( 7w + w = 8w ) days. Therefore, in ( w ) weeks and ( w ) days, there are ( 8w ) days.
-36 + 2w = -8w + w -36 + 2w = -7w -36 = -7w - 2w -36 = -9w w = -36/-9 = 4
