Answer:
263.12 radians
Step-by-step explanation:
The length of the rear wheel is given by:
![L=2\pi r\\L=40\pi](https://tex.z-dn.net/?f=L%3D2%5Cpi%20r%5C%5CL%3D40%5Cpi)
The distance traveled by the lawn tractor in 23 seconds is:
![d=13\frac{miles}{hour} *63360\frac{inch}{miles}*\frac{1\ hour}{3600\ seconds}*23\ seconds\\ d=5,262.4\ inches](https://tex.z-dn.net/?f=d%3D13%5Cfrac%7Bmiles%7D%7Bhour%7D%20%2A63360%5Cfrac%7Binch%7D%7Bmiles%7D%2A%5Cfrac%7B1%5C%20hour%7D%7B3600%5C%20seconds%7D%2A23%5C%20seconds%5C%5C%20d%3D5%2C262.4%5C%20inches)
The angle through which a wheel rotates is given by:
![A=\frac{d}{L}*2\pi \\A=\frac{5,262.4}{40\pi}*2\pi\\A=263.12\ radians](https://tex.z-dn.net/?f=A%3D%5Cfrac%7Bd%7D%7BL%7D%2A2%5Cpi%20%5C%5CA%3D%5Cfrac%7B5%2C262.4%7D%7B40%5Cpi%7D%2A2%5Cpi%5C%5CA%3D263.12%5C%20radians)
The wheel rotates through a 263.12 radians angle.

Step-by-step explanation:
42/7=6h
The sum of the polynomials is -11x - 3y^2.
In order to find this we must first collect all like terms. To start, we'll begin with all x^2 terms.
8x^2 - 9x^2 + x^2 = 0
Since these all cancel, we're left with no x^2 term. Next we'll do x terms.
-4x - 7x = -11x
The only thing left is -3y^2, which has no alike term. so we just include that in there.
-11x - 3y^2
