Answer:

Step-by-step explanation:

3(x - 2) = 5x - 14 (given)

3x -6 = 5x -14 (Distribute the "3" to "x" and "2")

-2x -6 = -14 (subtract "5x" from both sides)

-2x = -8 (Subtract "-6" from both sides)

x = 4 (divide both sides with "-2")

Which of the following expressions are equivalent to 2/x^6-y^6? Choose all that apply.

enot [183]

Answer:

A and C

Step-by-step explanation:

Equivalent expressions are expression which when simplified to lowest terms are equal.

Simplify each answer choice to find the expression which simplifies to $\frac{2}{x^6-y^6}$ .

A. Multiply the exponents 3*2 = 6. This is equal.

B. Multiply numerators and denominators. Here the numerator will be 1*1 = 1. It does not equal 2 in the numerator.

C. Here the numerator does equal 2. The denominator multiplies to $(x^3 - y^3)(x^3+y^3)\\x^6 -x^3y^3 + x^3y^3 -y^6\\x^6 - y^6$

This is equal.

D. The denominator will have three terms here when simplified. This will not be equal.
