Answer:
81
Step-by-step explanation:
9 to the 2nd power is 81
For this case, since the variation is direct then we have a relation of the form:

Where,
k: proportionality constant
To find k we substitute the following data:
y = 16 when x = 8
We have then:

Clearing the value of k we have:

Then, the equation is:

Substituting the value of x = 16 we have:

Answer:
The value of y for x = 16 is:

Answer : AB = 12
Explanation:
2x + 6 + 5x - 3 = 24
7x + 3 = 24
x = 3
AB = 2x + 6 = 2(3) + 6 = 12
