By the Pythagorean theorem, the missing side is -sqrt7. The definition of sin is side opposite over hypotenuse, so go into Q2 and make an angle and label the side opposite the angle with a 3 and the hypotenuse a 4. The other leg is -sqrt7 cuz x is negative in Q2. The cosine of an angle is the side adjacent over the hypotenuse, so the cos then is -sqrt7/4
We use the FOIL method here. First, Outer, Inner, and Last.
(5x)(x) = 5x^2
(5x)(-7) = -35x
(2)(x) = 2x
(2)(-7) = -14
5x^2 - 35x + 2x - 14
Now combine like terms.
5x^2 - 33x - 14.
This is the right answer because it is now in the form of ax^2 + bx + c

He biked 1 5/6 miles on Wednesdays which is more than the others. The order for the most to least would be as follows....
Wednesday: 1 5/6 miles
Monday: 1 4/6 miles (this can be simplified to 1 2/3)
Tuesday: 1 3/6 miles( this can be simplified to 1 1/2)
Thursday: 1 2/6 miles (this can be simplified to 1 1/3)
