12

Step-by-step explanation:

13*13=169

5*5=25

169-25=144

square root of 144 is 12

a = 5 ; b = 12 ; c = 13

Step-by-step explanation:

a and b represent the legs of the triangle and c represents the hypotenuse, or longest side, of the triangle. Knowing this, we can substitute the values in to solve for the other leg.

a² + b² = c²

⇒ 5² + b² = 13²

⇒ 25 + b² = 169

⇒ b² = 144

⇒ b = 12

the answer will be b x² +x-1

step-by-step explanation:

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
