M(5,7) is the midpoint of rs the coordinates of s are (6,9) what are the coordinates of r

(4, 5)

Step-by-step explanation:

Using the midpoint formula and equating x to 5 and y to 7, that is the coordinates of the midpoint M

let the coordinates of R be (x, y), then

0.5(x + 6) = 5 ( multiply both sides by 2 )

x + 6 = 10 ( subtract 6 from both sides )

x = 4

Similarly

0.5(y + 9) = 7 ( multiply both sides by 2 )

y + 9 = 14 ( subtract 9 from both sides )

y = 5

Thus coordinates of R = (4, 5 )

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 : )
