Everything = 180 degrees
2X = 180 - 40 - 40 -30
2x = 70
X= 35
The answer is A. If you substitute -2 and -8/3 for x, the answer is 0.
So x times y=3030
x and y=unknown
find the factors (factors of 6=2 and 3)
3030=2,3,5,101 so
two multiplication is
2 times 1515
3 times 1010
5 times 606
30 times 101
202 times 15
303 times 10
505 times 6
We have the following:

solving for x

The solution of x is equal to 28, therefore 12 is not a solution of the equation
First you would need to find out how many 9 payments of 58$ would be and that is 522. Then you would need to subtract the 522 and the 480 and your answer would be 42$ so the interest would be 42$
