C. x+x+10
Angles in a triangle add up to 180-50=130
130-10=120/2=x
x(60)+x(60)+10=130
Answer: 3.25 miles
Step-by-step explanation:
6 + 7 = 13
13 x .25 = 3.25
Hi. I begin by finding the positive factors of 14. They are: 1 x 14 and 2 x 7. None of those can be added to yield a negative number, so let's now instead consider their negatives: -1 x -14 and -2 x -7. Does either of these pairs, when added, yield -9? Yes: -2 and -7.
To be clear: -2 x -7 = 14; and -2 + -7 = -9.
So the answer is -2 and -7.
