Answer:
Two differences: A polynomial inequality (PI) can always be replaced by a PI with one side zero. A rational inequality (RI) can not, because you do not know the sign of the denominator; a(x)b(x)>c(x)d(x) can not safely be replaced by a(x)d(x)−b(x)c(x)b(x)d(x)>0 because b(x) and/or d(x) might change signs unexpectedly.
Step-by-step explanation:
Sum of all angles of a triangle = 180°
So,
angle E + angle O + angle C = 180°
=> 53° + 77° + C = 180°
=> 130° + angle C = 180°
=> angle C = 180° - 130°
=> angle C = 50°
X=4 because if you do 4 times 4 and 10^32 power you would then subtract that and that would then be you answer<span />
(1.) Part A
The Yellow Chalk because when you turn 2/6 into a new fraction (double it) its 4/12 and 4/12 is bigger than 3/12.
(2.) Part B
It's true because 5/12 is less than half of the bucket because the other half is 7/12
