So first write out the expression:

take two 10's from the top to cancel with the two 10's on the bottom.
3.9/1.3 is 3.
The answer is 3*10^3
Answer:
B: 0
Step-by-step explanation:
Note that (3, 1) satisfies the equation y = 2x - 5:
1 = 2(3) - 5
1 = 6 -5 = 1
Therefore, the distance between this point and this line is zero.
B is the correct answer.
The quadratic formula is -b + or - the square root of b squared - 4 times the a value and c value over 2a. So the roots would be -1.354249 and -6.645751. I believe these are the roots.
