Answer:
He is incorrect in this statement because 38 and 40 both have factors, other than 1 x itself. Prime numbers are numbers the only have 1 factor pair, and that is 1 x itself. Factors are the numbers you multiply to get the end result, and an example is 10x4=40. The factors of 40 are 8x5, 4x10, 2x20, and of course, 1x40. The factors of 38 are 2x19, and 1x38.

Answer:
The coordinates of the other points are (7,8)
Step-by-step explanation:
Mathematically, we have the midpoint formula as;
(x,y) = (x1 + x2)/2 , (y1 + y2)/2
(1,1) = (-5 + x2)/2 , (-6 + y2)/2
-5 + x2 = 2(1)
x2 = 2 + 5 = 7
(-6 + y2) = 2(1)
-6 + y2 = 2
y2 = 2 + 6
y2 = 8
The coordinates of the other points are (7,8)
