1+7=8 but not -8
-1+-7=-8 do this is right
A negative plus a negative will add up together since they are the same and make another negative number

Answer:
x² - 5x - 36
Step-by-step explanation:
Use FOIL (First, Outside, Inside, Last) to solve. x times x is x², so that is the first term of our trinomial. The outside terms are x times 4, or 4x. The inside terms are -9 and x, so -9x. The last terms are -9 times 4, or -36. We can add the like terms of 4x and -9x to get -5x. So, your trinomial is x² - 5x - 36.
The third one because square root of 13 is 3.606.
