I don't know for sure, but I think the answer is 200
area of rectangle= length × width
here I think I have to draw a rectangle (using insert you can easily get a rectangle)
-3x+9 = -3(2x+3) + 3(x-4)+1
distribute
-3x+9 =-6x-9+3x-12+1
add like terms
-3x+9= -3x-20
add 3x to each side
9 = -20
there are no solutions because 9 does not equal -20
Example: (1/5)/(4/13)=(1/5)*(13/4)=13/20
