Answer:
Choice C)
x^2 - 2x + 4 - 12/(x+2)

====================================================
Explanation:
To see how I got that answer, I have provided two attached images below. One of them shows the polynomial long division. The other shows synthetic division. Both are valid options to get to the same answer.
For each method, I used 1x^3 + 0x^2 + 0x - 4 in place of x^3 - 4 so that the proper terms could align.
i believe the answer is 19
Answer:
8 * sqrt2
Step-by-step explanation:
the area of a square can be found by squaring the length of the diagonal and then dividing it by 2. 16^2 / 2 = 128. if the area of a square is 128, each side is sqrt 128 = 8 * sqrt2
Well if we have two angles, LMT and TMN, that make up LMN, then the sum of LMT and TMN should equal LMN.
144 + 23 = 167 degrees.
Hope this helps!
