You can place two squares side by side
Technically a square is a rectangle so that counts as a rectangle
The answer is 523.6 and all you have to do is round it to the nearest hundredth
(-x²-2x+6)+(-9x²-7x+6) = -x²-2x+6-9x²-7x+6 = -10x² - 9x + 12
you pay x for ten laps an you pay y for every additional lap you just multiply y by seven an add x
so all an all your answer would be (B)
