$187.52 is 6.24% off of 200 and the amount saved is $12.48. If this is not what you meant let me know. The math is $200 × (1 - 6.24) = $187.52. Hope this helps!
We have been given an expression 
. We are asked to factor the given expression by grouping.
First of all, we will make two groups of our expression as:
Now we will factor of greatest common factor from each group.
Now we will factor out common terms 
as:
Therefore, the factorized form of our given expression would be .
The mean decreases, think about it, if every single value in a data set was decreased by the same number, the average would also go down by the same number
The median would also go down, because the value in the middle of the data set would now be smaller than before
The mode would also decrease, because the value that showed up the most in the data set has now also been decreased
The range, however, stays the same. If the lowest value in a data set was 3 and the highest was 10 and you subtracted 2 from each value in the data set, you would have the lowest at 1 and the highest at 8. But, 10-3 still equals 8-1, so the range is unchanged
The length is (3/5 -1/5)=2/5
the height is also 2/5
area: length * height =2/5 *2/5=4/5
D is correct.
B. your answer is an angle
