A. Factor 28 + 7g  7(g <span>+ 4) 

add 
28 </span><span>+ 7g 

= 7 (g </span>+ 4)

B. (12r + 15) – 65 Remove parentheses
12r+15-65

= 12r - 50 

C. 24 – (8p – 12)

24 - (8p - 12) = -8p + 36 

24 - (8p - 12)  -(8p - 12) 8p + 12

= 24-8p+12

Simplify 24-8p+12 

Group like terms
-8p+12+24

Add the numbers  12+24=36

Answer is -8p+36

Please help me out :)
Jobisdone [24]

Answer:

Q= (5,4)

Step-by-step explanation:

The x value went up by 4 units and the y value up by 6 units from the first point to the midpoint. Since the midpoint is equal distance from both points, we know it will go up by the same amounts for Q.

so 1+4= 5

-2+6= 4

<h3>What is a matrix?</h3>

Matrix is defined as the arrangement of the numbers variables and expressions in the table as rows and columns.

The multiplication of the matrix will be calculated as:-

M = \dfrac{1}{2}\left[\begin{array}{cc}12&64&\\78&30&\\\end{array}\right]

M  =    \left[\begin{array}{cc}\dfrac{12}{2}&\dfrac{64}{2}&\\\dfrac{78}{2}&\dfrac{30}{2}&\\\end{array}\right]

M =     \left[\begin{array}{cc}8&32\\39&15&\\\end{array}\right].

Therefore the correct answer is option C which is  \left[\begin{array}{cc}8&32\\39&15&\\\end{array}\right].
