Answer:
<h3>x = 7</h3>
Step-by-step explanation:
The sum of the adjacent side of the trapezium is 180 degrees, Hence;
97 - 3x + 69+5x = 180
166 + 2x = 180
2x = 180 - 166
2x = 14
x = 14/2
x = 7
Hence the value of x is 7

Answer:

Step-by-step explanation:
the minimum of f is for x = 1 and f(1)=0
f is decreasing for x<=1 and increasing for x>=1
so the domain is 

x>=1 so x is positive and we can take the square root
so
