Answer:
<em>(3) 2-8-4</em>
<em></em>
Step-by-step explanation:
Sulphur has an atomic number of 16
sulphur can exist in 3 different excited states of +2, +4 and +6
electronic configuration of sulphur is 2,8,6
when excited, <em>it loses 2 electrons to enter the +2 state</em>
in the +2 state, the electronic configuration will be <em>2,8,4</em>
Let x be the month on which the fee for two plans are equal.
Therefore,
150 + 10x = 50 + 30x
10x - 30x = 50 - 150
-20x = -100
x = 5
Cumulative cost = 150 + 10(5)
= 150 + 50
= 200
Hence, Karan will pay a cumulative cost of $200 dollars with either plan to go to the gym for 5 months.
Choice A is correct
BC=DC
the two triangles share one angel C
the two triangles each have a right angle
so they are congruent according to Angle-Side_Side Theorem
3x³+6x²+9x+10
or
6x³+9x²+3x+5
