Add the x-coordinates and divide by 2.
Add the y-coordinates and divide by 2.
x-coordinate of midpoint: (-3 + 5)/2 = 2/2 = 1
y-coordinate of midpoint: (4 - 8)/2 = -4/2 = -2
Answer: (1, -2)
You will distribute the negative sign inside the parenthesis, so the whole thing simply to t-8-t+15, and if you combine like term you get 7
<span>The factors of 12 are : 1, 2, 3, 4, 6, 12.
The factors of 15 are : 1, 3, 5, 15.
1 and 3 are the only common factors (numbers which are factors of both 12 and 15).</span>
<span>Therefore, the highest common factor of 12 and 15 is 3.</span>
