C = 12.2
Not sure if it’s the pythagorean theorem..
The opposite of 17.2 from 0 on a number line would be -17.2.
To simplify the problem it would be: -18xy+18y^2
The first answer is 1120,467,654,444,800
the second answer is 17,183,431,198,720
Answer:
d. 140
Step-by-step explanation:
QTR is a 180 degree angle, so we can assume PTR is 140 degrees because (x+28) is (12+28)= 40
