20 points! Simplify: 2y(2y+3yx^{2} )-y^{2} (3-y) please show work!
arlik [135]

Answer:

8x2y - 6x2 - 8xy2 - y2

Step-by-step explanation:

Equation at the end of step  1  :

 (((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+(8x•(y2)))-3y2)

Step  2  :

Equation at the end of step  2  :

 (((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+23xy2)-3y2)

Step  3  :

Equation at the end of step  3  :

 (((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-3y2)-(x2+8xy2-2y2)

Step  4  :

Equation at the end of step  4  :

 (((((5•(x2))•y)-(5•(x2)))+3x2y)-3y2)-(x2+8xy2-2y2)

Step  5  :

Equation at the end of step  5  :

 (((((5•(x2))•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)

Step  6  :

Equation at the end of step  6  :

 ((((5x2•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)

Step  7  :

Final result :

 8x2y - 6x2 - 8xy2 - y2

tankabanditka [31]

Answer:

B. Mode

Step-by-step explanation:

The mode of any distribution is the value with the most recurrence in a given set of data or distribution. It is also possible that such given set of data have more than one mode. They can be bimodal, that is having two modes and they can be multimodal, that is having multiple modes.

For example, in a given set of data like 2,3,3,5,6,7,7,7,7,7,9, the most occurring value or entry is 7 and the mode of the set of data is said to be 7.
