Answer:

Step-by-step explanation:
<u>Operation of Functions</u>
Given:


The sum of (f+g) (x) is:

We cannot operate with the expression inside the absolute bars, thus:

To find the zeroes you make the function equal to zero and then solve.

Then factor out the x to get a quadratic inside the parentheses.

Factor the inside quadratic formula.

Lastly, use the zero product property to solve.

Answer:
1). x = 81
2). x = 84
Step-by-step explanation:
1). By applying geometric mean theorem in the given triangle,

56x = (18√14)²
56x = 4536
x = 
x = 81
2). By applying geometric mean theorem,

16x = (8√21)²
16x = 1344
x = 
x = 84
