How would the expression x cubed minus 8 be rewritten using the difference of cubes?

Answer: (x - 2)(x² + 2x + 4)Factor the difference of cubes:a³ - b³ = (a - b)(a² + ab + b² )note 8 = 2³ = 8 ⇒ b = 2 , with a = xSox³ - 8= x³ - 2³= (x - 2)(x² + 2x + 2²) = (x - 2)(x² + 2x + 4)


Can you make a pyramid using multilink cubes?

No, because you would not get the apex.


How many arrangement can you make with 5 cubes?

If you have 5 distinct cubes, the number of arrangements can be calculated using the factorial of the number of cubes. Thus, the total arrangements would be 5! (5 factorial), which equals 120. If the cubes are identical, there would be only 1 arrangement.


How would you factorise x2-49?

To factorise ( x^2 - 49 ), you can recognize it as a difference of squares. This expression can be rewritten as ( (x)^2 - (7)^2 ). Using the difference of squares formula, ( a^2 - b^2 = (a - b)(a + b) ), we factor it as ( (x - 7)(x + 7) ).

Does lemon help melting ice cubes?

Lemon does not have any unique properties that would help melt ice cubes faster. The primary method for melting ice cubes is through heat transfer, which can be achieved by using warm water or placing the ice cubes in a warmer environment.

What would happen if displacement was calculated using a value other than the center of mass?

The final expression for displacement will get more complicated expression.


Does cos (x plus y) cos x plus cos y?

The expression (\cos(x + y) \cos x + \cos y) does not simplify to a standard identity. Instead, it can be rewritten using the angle addition formula for cosine: (\cos(x + y) = \cos x \cos y - \sin x \sin y). Therefore, the original expression is not generally true, and its simplification would depend on specific values of (x) and (y).
