-2x - 1 - X+ 7 simplified

-2x + 6 -X

Step-by-step explanation:

7 - 1 = 6

So your equation would look like this:

-2x + 6 - X

Since you capitalized on the X I don't think you can do any further simplification.

Unless that was an accident :|

(which they probably will) :)

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
