A. cos^2 x cscx-cscx= -sinx
B. csc^2x + sec^2x = 1
C. sinx(cotx + tanx) = secx
D. cos^2x - sin^2x = 1- 2sin^2x

The Answer is B.

Step-by-step explanation:

I just had this question and the answer came out as B

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

−3
