Model the problem with algebra tiles. Then use the model to write an algebraic expression that represents the situation. Colton practiced two more hours.

How can you model this situation?

The situation can be modeled with algebra tiles by

and

.

The situation can be represented as an algebraic expression as

.

step-by-step explanation:

option b  

step-by-step explanation:

we know that

the distance from point n to lm in the figure is equal to the distance of the perpendicular line to lm that passes through the point n

so

the distance is equal to the segment no

> given problem

therefore

the distance from point n to lm is equal to
