Need some help with this problem, cant really figure out how to do this

Step-by-step explanation:

Given:

Required:

Simplify

SOLUTION:

Add like terms together

-2.5f and 0.3f are like terms. If you add them together you'd get -2.5f + 0.3f = -2.2f

-16 and -9 are like terms. Adding toghter, you'd get -16 +(-9) = -25

So we would have:

answer: 26

step-by-step explanation:

well, michelle wanted to measure the height of her school's flagpole she placed a mirror on the ground 48 feet from the flagpole then walk backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft from the mirror using similar triangles find the height of the flagpole to the nearest tenth of a foot find the geometric mean of them pair of numbers. its easy math

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
