Answer:
The total surface area is: 468 in^2 which agrees with answer a)
Step-by-step explanation:
The three lateral faces of the prism are rectangles, and the sums of their areas give:
12 * 10 + 9 * 10 + 15 * 10 = 360 in^2
The area of each triangular base (notice it is a right triangle) is given by:
9 * 12 / 2 = 54 in^2, so we add TWO of these to the three rectangular faces:
Total surface = 360 in^2 + 2 * 54 in^2 = 468 in^2
Answer:
The expression used to represent g(x) as inverse of f(x) is 
Option B is correct.
Step-by-step explanation:
We are given:

We need to find the expression that could be used to verify g(x) is the inverse of f(x).
We know that
is inverse of function
So placing value of f(x) in g(x)

So, the expression used to represent g(x) as inverse of f(x) is 
Option B is correct.
We can also solve to prove that 

Answer:
N= -4
Step-by-step explanation:
3 is 1/6 of the numbers on the cube so you do 642 X 1/6 and get 107 as the answer
My answer is this but I’m not sure
