Answer:

Step-by-step explanation:

$sin^2 \ x + sin ^2 \ x + 2cos^ 2\ x = 2\\\\2sin^2 \ x + 2 cos^2 \ x = 2\\\\2 ( sin^2 \ x + cos^2 \ x ) = 2 \\\\2 \times 1 = 2 \\\\2 = 2 \\\\LHS = RHS \\\\Hence \ proved.$

What is 24x - 3 =7 I need to know because im in Detention and im at scool

ycow [4]

Why would someone give you the answer if you are in detention? I will tell you the first step which is to get rid of the -3 by adding positive three to both sides of the equation. Then from there, you should know what to do! Pay attention in class, and stop giving your teacher trouble!

HELP PLEASE!!! WORTH 8 points!!!!

vichka [17]

It seem like it's listing the factors and not the roots. If the given factors are x-2, x-(1+sqrt(5)), and x+3i

Then this means that x-(1-sqrt(5)) is another factor. So it looks like choice B is the answer. I'm using the idea that if x-(a+b*sqrt(c)) is a factor then so is x-(a-b*sqrt(c)).
