What is the sum of the given polynomials in standard form? (x2 – 3x) + (–2x2 + 5x – 3) –3x2 + 8x – 3 –x2 – 2x – 3 3x2 – 8x + 3 –x2 + 2x – 3

Are triangles the congruent? write the congruency statement.what is the congruency that proves they are congruent? what is the perimeter of ∆pqr?

Need so much on this one how many yards?

]supplementary angles are two angles that add up to . • complementary angles are two angles that add up to degrees. • adjacent angles share a and a • congruent angles have the measure. • an triangle has one angle that is greater than 90 degrees. • a triangle with angles 45°, 45°, and 90° would be a triangle
