1 and 13. I think you meant to make 2 as an exponent, otherwise it would not be any of the following if it isn’t.
        
             
        
        
        
A) 0.955 and 199/200
B) 1.40 or 1.4 and 1 2/5
C) 0.90 or 0.9 and 9/10
        
                    
             
        
        
        
Answer:
Carrying forward.
Step-by-step explanation:
- When regrouping is done to add the numbers where results in a more than 2 digit and one digit is placed to left Colum is called as carrying forward. As regrouping refers to carrying the place values in order to perform operations like addition or subtraction.
 
        
             
        
        
        
The interior angles of a parallelogram will always equal 360. The interior angles of a triangle are 180 if it is a equilateral triangle then the angles are 60 degrees each. You know 2 sides of parallelogram. The 100 degree and 90 degree. You can find the one opposing the x because it’s on a straight line and a straight line is 180 degrees if a triangle is 60 degree angle then the opposing angle to complete the straight line must be 180-60 so you get 120. You now know 3 sides. 120, 90 and 100
They should add up to be 360 so you can set up an equation like so 
120+90+100+x=360
And x = 50
        
                    
             
        
        
        
Answer:
x = 1.19258 and x = −4.19258
Step-by-step explanation:
The given equation is :

Keep x terms on the left and move  the constant to the right side  by adding it on both sides.

Take half of the x term and square it.

then add the result to both sides

So,
x = 1.19258 and x = −4.19258
Hence, this is the required solution.
