I think this is what you mean. I don't know why the Latex didn't work. Good for you that you can use it.


 Reduce the 4/28 to 1/7

 Make the 2 minuses into a +

 56 is the common denominator.

Answer = [23 + 21 + 8] / 56 = 52 / 56 = 13 / 14 When both numerator and denominator are divided by 4
13 / 14 <<<< answer.
 
        
        
        
Answer: 75 square 
Explanation: 
Width is X 
Length is 3x 
Every rectangle has 2 equal widths x 2 equal lengths 
Perimeter is 2x + 2(3x) = 40 
X = 5 
Width is now 5in 
Length is now 15in 
Area is 75in^2 
Half of a perimeter is length + width, which equals to 20in 
4x = 20, CX = 5 
= 75 sq

Answer: Jennifer didn't randomly assign participants to the control and experimental group. 
Step-by-step explanation: In the scenario discussed above, Jennifer failed to perform a random assignment of the participants who took part in the survey, that is the experimental group, those who receive the treatment and the control group, those who don't. Random assignment is required in other to address the issue of bias in our experiment. She was supposed to perform a random assignment of the participants to the two groups instead of asking them to make a choice.
