3x^2 + 5x + 2
a = 3 , b = 5 , c = 2
Start by mulitplying a*c = 3 * 2 = 6
Now find two number that multiply to 6 and add up to b or 5
We could use 2 and 3 because ....
3 + 2 = 5
3 * 2 = 6
Now you rewrite....
3x^2 + 3x + 2x + 2
Now pull out common factors...
3x ( x + 1 ) + 2 ( x + 1)
The factors of this expression is ( 3x + 2 ) ( x + 1)
Monthly amount, M = $102×4 = $408.
Also, yearly amount, Y = M×12 = $408×12 = $4896
It is given that 25% of the cost is contributed by Marcus.
Amount Marcus paid
Therefore, his employer contribution annually for coverage is $( 4896 - 1224)=$3672.
Hence, this is the required solution.
1. C.
The rule of powers is that when a parenthesis is raised to a power, you multiply the two numbers. Since it is being raised to the second power, it needs to have a 10 in the parenthesis. That would make 20.
2. B
Firstly 10^2 = 100, so we know that the number must be 10. That leaves us with just A and B. Then we know the same thing from the previous equation, that they need to be multiplied together.

For each number,there is a 16 probability of rolling it (so 16 for the 1 and also 16 for the 4)
