Answer:
P(w) = 9w+5
Step-by-step explanation:
You see every week there is an increase of 9, and it starts at 5. That's all you need to know for a linear equation.
Diagonals congruent: rectangle, square, isosceles trapezoid
Perpendicular bisectors: Rhombus, Square
This has exactly two solutions.
You can find the number of a solutions that a problem has by its highest power of x. Since x is raised to the 2nd power in here, it has two solutions. In some cases, these solutions will be irrational, double roots, or non-real, but there will still be two of them regardless.
