First you have to figure out what IS 1/4 of 52, so all you need to do is put in your calculator 52 X .25 and get your answer
Then type in all of the four questions underneath into your calculator and chose the one that does NOT result in your original answer
Answer:
3
Step-by-step explanation:
Answer: x=25, y=19
Step-by-step explanation: Because the triangle is equilateral, all the angles must be equal to 60 degrees. So 2x+10=60. 2x=50 and x=25. Then the same thing: 3y+3=60. 3y=57, y=19.
The quadratic formula is 
.
From the problem, a is 1, b is -1, and c is 12. Plugging in these values gives:
Because there is a square root of a negative number, there is no solution.
