I like to always factor out the negative first, so that we will have our first term be positive:
So it can be rewritten as this: -(x^2-3x-28)
Then we need to find two numbers that multiply to -28, but add up to -3.
Those two numbers are -7 and +4.
So we can rewrite as: -(x-7)(x+4)
Since two of the sides are perpendicular that means they both have a right angle so the correct answer is C.
0, sqrt(9), 16.00, -4, -2, and -5 are all whole numbers because they all simplify to numbers without decimals
This should be simple, add the Amounts of snow for the first week
4.32 + 6.86 = 11.18
-------------------------------------------------------
The subtract the amounts of snow from each week
11.18 - 7.89 = 3.29
----------------------------------------
C.) 3.29 is your answer
