x = -1
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
From the question, the values of x, y and z are as follows.
x=15, y=3 and z= -2
Now, we are to find the value of the expression

we substitute the values of x, y and z into the expression and simplify




Therefore, value of

Write and solve an equation of ratios based upon the fact that the small and large triangles shown are similar:
5 6
---- = ---------
14 6 + x
Then 30 + 5x = 84, and 5x = 54, and so x = 54/5, or 10.8, or 10 4/5.
