What is the completely factored form of x3 â€"" 64x? x(x â€"" 8)(x â€"" 8) (x minus 4) (x squared 4 x 16) x(x â€"" 8)(x 8) (x â€
Vadim26 [7]

The factored form of an equation is done by rewriting the equation in simpler forms.

The completely factored form of x^3 - 64x is x(x-8)(x + 8)

The expression is given as:

x^3 - 64x

Factor out x from the expression, x^3 - 64x

x^3 - 64x = x(x^2-64)

Express 64 as 8^2

x^3 - 64x = x(x^2-8^2)

Express the expression as a difference of two squares

x^3 - 64x = x(x-8)(x + 8)

Hence, the completely factored form of x^3 - 64x is x(x-8)(x + 8)

Which quantity is proportional to 18⁄3? Check all that are true. 90⁄16 36⁄6 72⁄12 6⁄1 36⁄12
NikAS [45]

Answer:

36/6, 72/12, and 6/1

Step-by-step explanation:

18/3=6, so we just need to find the fractions that simplify into 6 (we reduce fractions by dividing the numerator and denominator by the greatest common factor, in this case the number must be whole, so we are just going to divide the numerator by the denominator). 90/16=5.625, it does not equal 6, so it is not proportional to 18/3, this is also true for 36/12=3. 36/6=6 so it is proportional, so is 72/12=6 and, obviously 6/1=6 so it, too, is proportional to 18/3.
