Answer:
5-(-3y+3z)-3(-5z-y) = 6y+12z+5
Step-by-step explanation:
5−(−3y+3z)−3(−5z−y)
Distribute:
=5+3y+−3z+(−3)(−5z)+(−3)(−y)
=5+3y+−3z+15z+3y
Combine Like Terms:
=5+3y+−3z+15z+3y
=(3y+3y)+(−3z+15z)+(5)
=6y+12z+5

Answers: PA and PC</h3>
Explanation:
Segments PB, PA and PC are all radii of the same circle. We call this circle the circumcircle, with point P as the center of this circle.
To determine the location of P, we construct at least two perpendicular bisectors as the diagram shows. Segments PR, PS and PT are perpendicular bisectors of AB, AC, and BC in that order.
We will assume A×B = B×A and show that A and B are necessarily the same.
Assume A×B = B×A. Let a ∈ A and b ∈ B. Then (a,b) ∈ A×B. Since A×B = B×A, we have (a,b) ∈ B×A. That is, a ∈ B and b ∈ A. Therefore, a ∈ A implies a ∈ B and b ∈ B implies b ∈ A. So A = B, as we had set out to do.
Where's the picture? How am I supposed to solve with no picture? :/
