Which function defines (f + g) (x)?
f(x)= 5/x +12
g(x) = square root(x-3) + 10
options:
A. (f + g)(x) = 5/x + square root(x-3) + 22
B. (f + g)(x) = (square root(x-3) + 5 / x)+22
C. (f + g)(x) =5/x - square root(x-3) +2
D. (f + g)(x) = 5/x + square root (x) +19

Part a what is the area of triangle i? show your calculation. part b triangles i and ii are congruent (of the same size and shape). what is the total area of triangles i and ii? show your calculation. part c what is the area of rectangle i? show your calculation. part d what is the area of rectangle ii? show your calculation. part e rectangles i and iii have the same size and shape. what is the total area of rectangles i and iii? show your calculation. part f what is the total area of all the rectangles? show your calculation. part g what areas do you need to know to find the surface area of the prism? part h what is the surface area of the prism? show your calculation. part i read this statement: “if you multiply the area of one rectangle in the figure by 3, you’ll get the total area of the rectangles.” is this statement true or false? why? part j read this statement: “if you multiply the area of one triangle in the figure by 2, you’ll get the total area of the triangles.” is this statement true or false? why?
