Subtract 7x^2+4x-9 from 5x^2+10x- express results as a trinomial in descending degree order.

Solve by any method (graphing, substitution or linear combination)y = x - 82x + 3y = 1a) (2, -6)b) (5, -3)c) (4, -4)d) (0, -8)i figured it out. the answer is (5, -3)

1. are the corresponding angles congruent 2. find the ratios of the corresponding sides 3. is triangle jkl congruent to triangle rst? if so what is the scale factor

Solve the triangle. a = 21°, c = 105°, c = 5
