C. 5x-1

Step-by-step explanation:

We are asked to find:

(f+g)(x)

This basically is asking us to add f(x) and g(x)

(f+g)(x)=f(x)+g(x)

We know that f(x)=3x-2 and g(x)=2x+1

f(x)+g(x)

(3x-2)+(2x+1)

Combine like terms. Add all the terms with variables, then add all the terms without variables.

(3x+2x) + (-2+1)

5x+(-2+1)

5x+-1

5x-1

(f+g)(x)=5x-1

Therefore, C. 5x-1 is the correct answer choice.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
