How do you simplify 3(j-2k)+4 ?​
masha68 [24]

Answer: 3j-6k+4

Step-by-step explanation:

First you have to distribute the 3 to the j and the -2k since they are both in the parentheses. So it would look like (3*j) +(-2k*3)+4 and if you simplify that it is 3j-2k+4. After that there are no like terms so that is your answer.

3 QUESTIONS WILL GIVE BRAINLIEST<br> (50 POINTS) PLEASE HELP
grandymaker [24]

Answer:

<h2>Q 11. A and E</h2><h2>Q 12. A</h2><h2>Q 13. 4/3 cups of sugar</h2>

Step-by-step explanation:

The points (1, 3) and (15, 45) are proportional to point (3, 9) since they correspond with each other so if you multiply the point (1, 3) by a factor of 3, it would be (3, 9). If you divided the point (15, 45) by a factor of 5, it would be (3, 9).

In this equation, 2.95 represents the price of the gallons since it is being multipied by g, or the number of gallons.

If you were to multiply 2/3 cup of sugar and 1/2 cup of flour by 2, I would get 4/3 cups of sugar and 1 cup of flour. Why did I do this? Well, she uses 1 cup of flour so you can divded 1 by 1/2 is which 2.

Hope this helps, you can ask me why certain choices were not correct if you'd like.

What values of x make the equation x2 + 9x – 22 = 0 true? Check all that apply. –11 –2 0 2 11
Marat540 [252]
Answer:  x = 2 ;  -11 .
___________________________________
Explanation:
_____________________________________________
Given the equation:
_____________________________________________
  x² + 9x −<span> 22 = 0  ;  Solve for:  "x" ;
_____________________________________________

Let us factor the "left-hand side" of the equation:
_____________________________________________
  "x</span>² + 9x −<span> 22"  ;
_____________________________________________

What are the factors of "-22"" that add up to "positive 9" ?
_____________________________________________
  Let us list the factors of "-22" :
____________________________________________
-2, 11;  </span>→ -2 + 11 = 9 ;<span>
-11, 2;  </span>→ -11 + 2 = -9 ;<span>
____________________________________________

So we have:  "-2" and "11" ;
____________________________________________
So;   </span>  "x² + 9x − 22" ; factors into " (x−2)(x + 11)" ;
____________________________________________
We have:  (x−2)(x + 11) = 0 ;

So:  x − 2 = 0 ;  

Add "2" to each side of the equation; 

     x − 2 + 2 = 0 + 2 ; 

          x = 2 ; 
___________________________________
   x + 11 = 0 ;

Subtract "11" from each side of the equation;

   x + 11 − 11 = 0 − 11 ;

      x = -11 ; 
___________________________________
 Answer:  x = 2 ; -11 .
