sorry I didn't know that answer

Answer 2

Answer:

13

Explanation:

3[sin x + cos x ]^4 + 6[sin x + cos x ]^2

+ 4[sin ^6 x + cos ^6 x]

we know that ,

sin theta + cos theta = 1.

3[sin^2 x + cos^2 x ]^2

+ 6[sin^2 x + cos^2 x ]

+ 4[sin ^2 + cos ^2 x ]^3

3×1^2 + 6 × 1 + 4 ×1^3

3+6+4

=13

13 is your answer

hope it helps mark me as brainliest
