What is the solution sets of the equation √9 + 10 = x ?

Solve for 'x' by simplifying both sides of the equation, then isolating the variable.

x = 13

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

idk what the heck he answer is, i’m just putting this here so i finish my account
