Answer:
You cannot add like terms like that.
Step-by-step explanation:
The terms are supposed to be added together, by combining them like that you are multiplying them together.
The answer to this equation is -1/15
We can solve for the value of x using pythagorean theorem

where c is the hypotenuse ( in this case is 15) and a, b are the other legs of the triangle ( in this case is 8 and x).
Let's substitute the given values to the formula

Now please follow this solution to solve for x in:
Step-by-step explanation:
a.) All real numbers x greater than 2
===> X > 2
b.) 6 more than a number k is less than or equal to 12
===> 6+k =< 12
