Jack broke apart 5x 216 as (5x 200) + ( 5× 16) to multiply mentally. what strategy did jack use?

Funny because i use the same strategy almost every time.

But as for strategy, maybe I would say distributivity, since multiplication is distributive with respect to addition.

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.

solving with completing the square

i can't solve unless i know what the line is
