The side length, s, of a cube is x – 2y. If V = s3, what is the volume of the cube? x3 – 6x2y + 12xy2 – 8y3 x3 + 6x2y + 12xy2 +
otez555 [7]

V = x³ - 6x²y + 12xy² - 8y³

V = (x - 2y)³

   = (x - 2y)(x - 2y)(x - 2y) ( expand first pair of factors )

   = (x² - 4xy + 4y²)(x - 2y) ( multiply terms in first by terms in second )

   = x³ - 4x²y + 4xy² - 2x²y + 8xy² - 8y³ ( collect like terms )

  = x³ - 6x²y + 12xy² - 8y³

-3x + y = 3
3x + 2y = -12
-----------------add
        3y = - 9
         y = -9/3
         y = -3

3x + 2y = -12
3x + 2(-3) = -12
3x - 6 = -12
3x = -12 + 6
3x = - 6
x = -6/3
x = -2

solution is (-2,-3)

Calculate the product below and give your answer in
krok68 [10]

Answer:

(1.5*10^{0})*(2.0*10^{-5})=3.0*10^{-5}

Step-by-step explanation:

we know that

When multiply two numbers in scientific notation, multiply their coefficients and add their exponents.

we have

(1.5*10^{0})*(2.0*10^{-5})=(1.5*2.0)*10^{(-5+0)}=3.0*10^{-5}

therefore

(1.5*10^{0})*(2.0*10^{-5})=3.0*10^{-5}
