In Hayden's Theory of All Unknown Numbers, what is the answer to this equation? 61x² + 17 = ?

I'll give brainliest to whoever gets it right.

Find the area of a parallelogram with base 15 yards and height 21 2/3

List x1, x2, x3, x4 where xi is the midpoint endpoint of the five equal intervals used to estimate the area under the curve of f(x) between x = 0 and x = 10.

]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
