Why the expression -6(5 - k) and 6k - 30 are equivalent.

Step-by-step explanation:

-6(5 - k) and 6k - 30  

-6(5 - k)                      Use the Distributive Property.

-6*5  -6*-k

-30 + 6k                     This can be written differently.

6k - 30                       So, both expressions are equivalent.

Distributive Property means to spread the multiplication through the addition.

Equivalent mean the same value, same amount.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
