In brackets everything has to multiplied by 3. It there is no sign between its always multiply!!!
this means that it has to be
3 x X + 3 x 11
this means that we can also multyplay 3 by 11 now.
and that equals to 33. There fore the expansion will be:
3 x X + 33
we can also simplify 3 x X which would be 3x (as I mentioned before, It there is no sign between its always multiply!!!)
so the expansion for 3(x+11) is 3x + 33
Answer:
D is the answer
Step-by-step explanation:
Total = Principal * (1 + rate/n)^n*years where "n" is the number of compounding periods
Total = 9,250 * (1 + .07/52)^52*5
Total = <span>9,250 * (1.0013461538</span>)^260
<span><span>Total = 9,250 * 1.418733571
</span>
</span><span>Total = 13,123.29</span>

assuming is square root of 55:
You can solve the square root and roound to the nearest number:
√55 = 7.41
Since the number after the decimal point is 4, the square root is closest to 7 than to 5.
You can also campare √55 with closest integers that are perfect square:
below 55, the closest perfect square is 49 = 7^2
above 55, the closest perfect square is 64 =8^2
55-49 = 6
64-55 = 10
Since 49 is closest to 55, it's square root is the nearest. (7)
