Straight away it can't be A or B because the last/ones digits aren't multiples of 5.
For something to be divisible by 9, add all the digits up and see if it is a multiple of 9:
This works for both C and D, as both numbers have digits which add up to 18.
However, only C is divisible by 6. D is an odd number and hence it is eliminated. For something to be divisible by 6, it must be divisible by 2 (an even number) and 3 (digits add to a multiple of 3). C does both.
Hence C is the answer.

The arithmetic sequence is the first one.
The answer would be 126 square inches because you have to break up the figures and figure out the area for each one so for the rectangle the area would be 75 because of the formula length times width then for the square it would be 16 because the formula is the side (squared) then for the last one the parallelogram it would be 35 because of the formula base times height. Hope this helped :)
The formula for finding the area of the circle works because they made it especially for it. I don’t really know how else to describe it, it simply just works.
Answer:
9) y>0 or y<−14 10) Each artwork sold for $34.4
Step-by-step explanation:
#9 is fairly easy, just plug in a calc and pull out ans.
#10 so he needs to make $300 + $44 in total to recover everything as he wants $300 more in profit. set up the equation:
$300 (Profit) + $44 (Initial) = 10 ( # of paintings) x (how much to be sold for
