The answer is A !!!!!!!!

the two segments AD and AB are equal therefore if you make the two equal to each other you will get the answer:

x^2+2=11 then you subtract two to put x squared on the side by itself
then you have x^2=9
then all you have to do is take the square root of 9 and x^2 and you get x=3
thefore the answer is A

Determine the midpoint between the two points x(4,-6) and y(-2,8)

ikadub [295]

Answer:

$p(a, b) = (1, 1)$

Step-by-step explanation:

Midpoint formula is

$p(a, b)=(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} )$ ---------------(1)

Here

$(x_1, y_1) = (4, -6) \ \ \ and \ \ \ (x_2, y_2) = (-2, 8)$

Substituting values in equation (1)

$p(a, b)=(\frac{4 - 2}{2}, \frac{-6 + 8}{2} )$

$p(a, b) = (1, 1)$
