Mis the midpoint of ab¯¯¯¯¯. m has coordinates (-3, -8) and b has coordinates (-1, 6). what are the coordinates of point a? a. (-5, -22) b. (-4, -1) c. (1, 20) d. (5, 22)

the equation to solve this type of question is :

( x1 + x2 ) divided by two = x value of coordinate

( y1 + y2 ) divided by 2 = y value of coordinate

together these equation will give you an answer for ( x , y )

in this case we would set it up like this :

x1 + x2 divided by two would look like this :

(x + -1) / 2 = -3

(x+ -1) = -6

x = -5

now solve for y

y1 + y2 divided by two :

(x+6) / 2 = -8

(x+6) = -16

x = -22

so the answer would be ( -5, -22 ) which is answer A  

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )
