Answer:4x+15

Step-by-step explanation: PEMDAS. First you multiply 12x3 and 9x2 so you get 36-18. Then you subtract 18 from 36 leaving you with 18. Then you combine 18 and -3, leaving you with 4x-15.

myrzilka [38]

Answer:

The answer is

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

$M = ( \frac{x_1 + x_2}{2} , \: \frac{y_1 + y_2}{2} )\\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(3, 2) and (9, 6)

The midpoint is

$M = ( \frac{3 + 9}{2} \: , \: \frac{2 + 6}{2} ) \\ = ( \frac{12}{2} \: , \: \frac{8}{2} )$

We have the final answer as
