The answers are A,B, and E. Hope this helps. :)
Step-by-step explanation:
Using cos ^2x+sin^2 x = 1
RHS = cos ^2x+sin^2 x = 1
Therefore,
LHS = cos ^2 x − cos ^4 x
= cos ^2 x ( 1 − cos ^2 x )
= cos ^2 x sin ^2 x
= ( 1 − sin ^2 x ) sin ^2 x
= sin ^2 x − sin ^4 x
= RHS
there are the ways to reach that are conduction,convection and radiation
Answer:

Step-by-step explanation:
Answer:
x=9 Hope this helps :)
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 3x from both sides.
Step 3: Subtract 6 from both sides.
Step 4: Multiply both sides by 3/(-8).
And you get x=9
