Evaluate 3 + (a + 4)(8 - b) when a = 5 and b = 6.
The value of the expression is

21

Step-by-step explanation:

you plug in 5 for a and 6 for b and solve.

translate k to n and reflect across the line containing jk.

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
