Answer:
Below in bold.
Step-by-step explanation:
5x - 3y = 1
3x- y = 5 Multiply this equation by -3:
-9x + 3y = -15 Now add this equation to the first equation:
-4x = -14
x = -14/-4 = 3.5.
Now substitute for x in equation 1:
5(3.5) - 3y = 1
-3y = 1 - 17.5
-3y = -16.5
y = 5.5.
Area of the rectangle y = (x+4)(-x+64)= -x²-4x+64x+256=-x² + 60x +256
y= -x² + 60x +256
