Prove that
(3-4sin^2A) (sec^2A-4tan^2A)=(3-tan^2A)(1-4sin^ 2A)​

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

answer: just subtact the units and then add the non negative : happy to
