The expression given is

The sum of the expression will be,

The sum will be
Just plug in -3 for x. So it will be -(-3)^+ 1
Which is 3^+1.
I'm confused by your ^ sign I'm not sure if this is supposed to be squared or not...? But just solve/simplify the equation.
Hope this helps!
46. Fortysix times 2 equals 92.
Peaches to plums. 15 divided by 3 is 5, 12 divided by 3 is 4.
Call the angles of depression D.
then tan(D)=20/30, or I
arctan(tan(D)) = arctan(⅔)
D=33.690. A is the answer
your calculator probably uses tan^-1 rather than arctan
