Starting with the formula for the difference of cubes, which pair of steps can be used to show that the expressions are
equivalent?

Step-by-step explanation:

First, we know that the formula for the difference of cubes is:

So, two show that both parts are equivalent, we just have to apply distributive property on the right side of the equation, because there's a product between a binomial expression and a trinomial expression, here commutative property doesn't make sense.

You can see that almost all terms are eliminated, except the first and last one, the other ones are just subtracted, they are equal but opposite.

Then, we reduce or combine like terms, having the equivalence.

Therefore, the correct answer is the first one.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

the aswere is the one with all 8's and the second one is with the 10,8 and 6
