What basic trigonometric identity would you use to verify that (sin² x + cos² x/cos x) = sec x?

a. sin x = (1/csc x)
b. 1 + cot² x = csc² x
c. cos² x + sin² x = 1
d. tan x = (sin x/cos x)

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
