3(2x + 4y - 2z) + 7(x + y - 4z)
Remove parenthesis.
Distribute 3 and 7 through the parenthesis

= 6x + 12y - 6z + 7x + 7y - 28z
Collect the like terms by adding their coefficients.

= 13x + 12y - 6z + 7y - 28z
Collect the like terms by adding their coefficients.

= 13x + 19y - 6z - 28z
Collect like terms by calculating the sum or difference of their coefficients. Use addition and subtraction rules to calculate the expression.

What is the midpoint of QR. Q(2,4) and R(-3,9)
Eduardwww [97]

Answer:

The answer is

( -  \frac{1}{2}  \: , \:  \frac{13}{2})  \\

Step-by-step explanation:

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

M = (  \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )\\

where

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

From the question the points are

Q(2,4) and R(-3,9)

The midpoint is

M = ( \frac{2 - 3}{2}  \:  , \:  \frac{9 + 4}{2} ) \\

We have the final answer as

( -  \frac{1}{2}  \: , \:  \frac{13}{2})  \\

Hope this helps you
