now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.

35/2 is it i think maybe

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions
