The sum of n and the product 3 times n = 12. What is n? (Show your equation and at least one step.)

N = 3

Step-by-step explanation: If you do the equation it comes out to n=4

n+3n=12

4n=12

n=3

You have to add the like terms then divide it so the variable is by itself. And whatever you do to one side, you have to do to the other

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
