Given points A(9, 3), B(–3, 6), and C(–7, –3). Which statements describe the vectors that include these points? Check all that apply. The magnitude of Vector A C is StartRoot 2 EndRoot.

The magnitude of Vector B C is StartRoot 97 EndRoot.

The magnitude of Vector A B is 3 StartRoot 17 EndRoot.

Vector A C = LeftAngleBracket negative 16, negative 6 RightAngleBracket

Vector B C = LeftAngleBracket 10, 9 RightAngleBracket

Vector A B = LeftAngleBracket negative 12, 3 RightAngleBracket

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

the answer is d

hope this

b

step-by-step explanation:

hello from mrbilldoesmath!

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

discussion:

in general, the factorization of a^3 + b^3 is

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

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

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

(a + b) (a^2 - a b + b^2)
