Answer:
3x - 6 = x + 9
2x - 6 = 9
2x = 15
x = 7.5

Answer:
√29
Step-by-step explanation:
We can call the given points A(3, 4) and B(-2, 6).
The right triangle with segment AB as a hypotenuse can best be drawn along grid lines. Then the vertical leg is the difference of y-coordinates: 6-4 = 2, and the horizontal leg is the difference of x-coordinates: 3 -(-2) = 5.
The Pythagorean theorem tells you the square of the hypotenuse is the sum of the squares of the legs.
AB² = 2² + 5²
AB² = 4 + 25 = 29
Taking the square root, we find the length of the line segment between the points to be ...
AB = √29
It’s 20 :) hope this helps
Subtracting a negative number is the same as adding a positive number
assume your number is n
n - (-10) = 6
n + 10 = 6
subtract 10 from both sides
