Answer:
x = 120
Step-by-step explanation:
First you want to get the equation into the form cosx = a
2 cos
=1
Divide both sides by two to get it into the form.
cos= 
Now, on your calculator, use the inverse of cos, to solve for .
= 
( )
= 60
Now you want to find x, so multiply both sides by 2.
x = 60 * 2 = 120
x can have many solutions; however, I have only given you one.
2x squared +1 - 7x squared +3
The answer is 10080 you can use a calculator for this
Sry but that’s too much which one would you like help on
