-63=7w
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

127w = 847w/7 = 84/7w = 12
7w - 4w - 6w = (7 - 4 - 6)w = -3w

Oh, isn't that a happy little math problem? When you see 4(7w), you can simplify it by multiplying 4 with 7, which equals 28. So, the expression simplifies to 28w. Just like painting a beautiful landscape, math can be a joyful experience when you break it down step by step.

25y2 - 49w2 = (5y)2 - (7w)2 = (5y - 7w)(5y + 7w)
56w2 + 17w - 3 = 56w2 + 24w - 7w - 3 = 8w(7w + 3) - 1(7w + 3) = (7w + 3)(8w - 1)
127w = 847w/7 = 84/7w = 12
7w - 4w - 6w = (7 - 4 - 6)w = -3w
7w=122 122/7= 17.43 w=17.43
3w + 4e + 7w - e3 = 10w - e
(5y + 7w)(5y - 7w)
