The second one. All the other ones have degree 6.
1)Find the lcd for 1/8+5/6
=2/24+5*4/24
since the denominators are equal, combine the fractions
=3+4*5/24
=23/24
2)Convert the mixed numbers to improper
=15/8*17/5
=255/40
=51/8
=6 3/8
3)1/9 divided by 3
1/3*9
=1/27
4) 2 3/5* 2 6/35
13/5*76/35
13*76/175
988/175
=5 113/175
89 divided by 6 = 14.83… the … are 3's but they go on forever, so you round to the hundredths and the 3 doesn't bump the 3 up so the answer is 14.83
Answer:
Hope that this is helpful.
Step-by-step explanation:
-3(2x-1)^2+12x^2
= -3[(2x-1)(2x-1)]+12x^2
=-3[2x(2x-1)-1(2x-1)]+12x^2
=-3(4x^2-2x-2x+1)+12x^2
=-3(4x^2-4x+1)+12x^2
=-12x^2+12x-3+12x^2
=(-12x^2+12x^2) +12x-3
=0+12x-3
=12x-3
