Me plz and thank you

B. (-1, -3)

Step-by-step explanation:

Given M(1, -4) as midpoint of , and G(3, -5),

let

Rewrite the equation to find the coordinates of G

and

Solve for each:

Multiply both sides by 2

Subtract 3 from each side

Multiply both sides by 2

Add 5 to both sides

Coordinates of G is (-1, -3)

395.84

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
