Answer:
The equation in standard form is:
x^2-40x-6000 = 0
Step-by-step explanation:
Let the length of the field be x yards.
Now the width of the field is 40 yards less than the length of the field.
Thus, the width of the field would be (x-40) yards
Now, to calculate the area of the field, we simply multiply the length of the field by the width of the field.
Hence;
Since the shape is rectangular, the area is the product of the length and that of the width
x(x-40) =6,000
x^2 -40x = 6,000
x^2-40x-6000 = 0

Answer:
Your bicycle has 22 gears.
Step-by-step explanation:
The number of gears in the bycicle is the number of combinatiors of a front sprocket and a rear sprocket.
For each front sprocket, there are 11 rear sprockets. There are 2 front sprocts.
So, the number of gears that your bicycle has is
2*11 = 22.
There's about 22 because if you extend it by going 3+1 and so on it wont hit 90 exactly but it'll be 91, so 22 small sliced pizzas and 23 large sliced pizzas
