Given polynomials p(x), q(x), and r(x), p(x) + (q(x) +r(x)) = (p(x) +q(x)) +r(x)
To verify the associative property of addition,
begin by finding the sum of the polynomials:
(3x + 4) + ((5x2 - 1) + (2x + 6))
x² +
X +

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0

The pyraminx is a rubik's cube-type toy in the shape of a tetrahedron. the pyraminx shown below has edges 15\,\text{cm}15cm long and vertical height h=12.2\,\text{cm}h=12.2cm. the triangle drawn with dashed lines is a right triangle. what is the distance rr? round your answer to the nearest tenth.
