The midpoint of the line segment whose endpoints are (3, 10) and (7, 8) is: (5, 9).

M = [(x2 + x1)/2] , [(y2 + y1)/2];

= [(3 + 7)/2] , [(10 + 8)/2];

= (10, 2) , (18, 2);

= (5, 9)

M = [(x2 + x1)/2] , [(y2 + y1)/2];

= [(3 + 7)/2] , [(10 + 8)/2];

= (10, 2) , (18, 2);

= (5, 9)

Determine the solution set of (x + 2)2 = 36.
{6, -8}
{4, -8}
{4, -6} **Weegy:** The answer is x=16. (More)

The solution set of (x + 2)2 = 36 is {4, -8}.

(x+2)^2=36

(x+2)=±6

x)=±6-2

x=4,or x=-8.

(x+2)^2=36

(x+2)=±6

x)=±6-2

x=4,or x=-8.
