The answer to your question is below.
Step-by-step explanation:
14.- Use proportions to solve these problems.

14(x + 6) = 10(x + 9)
14x + 84 = 10x + 90
14x - 10x = 90 - 84
4x = 6
x = 6/4
x = 3/2
15.- 
10(x - 1) = 8(x + 2)
10x - 10 = 8x + 16
10x - 8x = 16 + 10
2x = 26
x = 26 / 2
x = 13
16.- 
5(x + 1) = 9(10/3)
5x + 5 = 30
5x = 30 - 5
5x = 25
x = 25 / 5
x = 5

Answer:
Nolan's time is 100 seconds.
Step-by-step explanation:
Kong took 85 seconds.
Nolan took x seconds.
Kong took 15% fewer seconds than Nolan, so Kong's time is 85% of Nolan's time.
Kong's time is
85% of x or 0.85x
Kong's time is 85 seconds
0.85x = 85
x = 85/0.85
x = 100
Nolan's time is 100 seconds.
It’s 38.67 because you have to use the formula square root and find the base which is B so you have to do hypotenuse reverse
