Step-by-step explanation:
The formula for calculate the distance between two points is:

In this case, given the points A(4,-6) and B(-4,2), we can identify that, we just need to substitute values into the formula in order to calculate the distance between the given points.
Thierefore, this is (Rounded to the nearest hundred):

Answer:
R = 4.2cm and D = 8.4cm
Step-by-step explanation:
The radius is 3.2 and the diameter is always twice much so its 8.4
Answer:
8 ≥ x+3 or x ≥ 12
Step-by-step explanation:
The sum of a number (additon) and 3 (x+3) is no more than (so less than or equal to eight) OR is more than 12 ( x is more than 12, x ≥ 12 )
