Answer:4 over 9 homie
Step-by-step explanation:
To get the width of its border we must first find the area of the border.
Total Area - Area of photo = Area of border
280 - (12)(18) = Area of border
Area of border = 64 sq cm
We now have a rectangle with a hole of 12x18 , so now we cut the area of the border such that we will have 2 (18xW), 2 (12xW), and 4(WxW) squares.
by this info we will have an equation
64= 2(18xW) + 2(12xW) + 4(WxW)
simply
4W^2 + 60W = 64
We then solve for W
and it would be
W = 1 cm Hope my answer would be a great help for you.

Mx + 4y = 3t
mx = -4y + 3t
x = (-4y + 3t) / m or x = -4y/m + 3t/m
