Answer:
Let's assign the variable x to cosA. The expression then becomes x² - 5x + 6. To factorize this we need to find two numbers that have a sum of -5 and a product of 6; these numbers are -2 and -3 so the expression becomes (x - 2)(x - 3). Since we know that x = cosA the final answer is (cosA - 2)(cosA - 3).
The answer to your question 4x-4y= -2 plus -9x-4y= -3 is -5 because in order to find the result of the two equations would be to add the solutions to both of them together.

He will be charged for 551 miles.
30283-29582=701 miles traveled in the rental vehicle.
150 of those miles are free; 701-150 = 551 miles he will be charged for.
2/5 + 1/2 = 0.9
0.9 in fraction form is 9/10!
Hope this helps!
