CLASSMATE #2

I will be using my birth date which is November 17, 1970. And the vocabulary words to describe my math discussion questions. 1. A= 11, B= -17, C= 70             My variables are going to be, a and b also my exponents are                                                  going to be 3 for both a and b. 2. A3 - b3 113 -173                                    I will now raise my integers to the given exponents of 3. 1331+ 4913                                I subtracted a negative and it is now changed to a positive.                                                  My final answer is 6,244    3. (a-b)(a2+ab+b2)                    I will plug in variable 11 and variable -17 (11--17)(112+11x-17+-172)        I will then raise all of the integers and multiply all of my factors. (11--17)(121+-187+289)            Next I will do my adding and subtracting. 28(223)                                     I will then multiply to get my final answer which is 6,244. 4. (b-c)                                     I will then plug in my -17 for my variable b, and also 70 for my                                                 variable c, and A for 11. (2b-a)                                                  I changed my double negative the divisor to positive. (-17-70) 2x-17+17 -87 -17 87 17                                           Both my numerator and denominator were negative so my answer is positive.                                                My final answer is a fraction and is in the lowest terms. In my first two algebraic expressions my answers were the same. I am assuming the answers were not a coincidence. I am thinking if the algebraic expressions are plugged in the right way the answers are going to be the same.
