ok consider a rectangle with two sets of equal sides
call one side of a set x
and one side of the other set y
we know she has 140 meters of rope so perimeter of the rectangle = 140
so 2x + 2y= 140
hence X = (140- 2y)/2
the dimensions have to satisfy the above equation
7+-3i is the correct answer because you add 4+3 because they are like terms then you add 2i+-5i because they are like terms
