=  = 11. A. 2/3÷-2/8 (2/3)(-8/2) -16/6=-8/3 When I was multiplying 3 and 2 I knew the answer was 6 so my mind put in the 6 where the 3 should be and multiplied.

22. A. and B. (-5)¯³ 1/(-5)³ 8¯² 1/8² A-I didn't keep the brackets. B-I forgot to drop the negative sign on the exponent.

23. Literal Coefficient-Letters Polynomial-Any expression consisting of the sum of two or more terms. I didn't do the necessary amount of studing and so got these two vocabulary terms mixed up.

24. A. (8d+3d²-12)+(2d²-10+d) 3d²+2d²+8d+d-12-10 5d²+9d-22 I replaced several addition signs for subtraction signs.

25. This is because you have to distribute (x^6) to the variables in the brackets. I didn't look at the question hard enough to realize it was a distribution question.

26. A. 2(ab+5) 2ab+10 I didn't realize that ab was the base.

27. B. (3x²-4)(2x-5) 6x²-15x²-8x+20 -9x²-8x+20 When multiplying 3x² and 2x I forgot that when there is no exponent that means that the exponent is 1.

29. B. -18j⁴k²-8j³k³+10j²k⁴ ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯= 3j²k+4³jk²-5³k³ -6j²k Instead of putting 4 and 5 at power of 3 I kept the 3 under the division line.
