After being rearranged and simplified, which equation cannot be solved using
the quadratic formula?

A. 5x² + 2x - 4 = 2x²
B. 2x² - 6x-7 = 2x²
C. 2x^2 - 3x + 10 = 2x+ 21
D. -3x + 10 = 2x^2

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

what are ur choices?

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
