Answer:
The equations shows a difference of squares are:
<u>10y²- 4x²</u> $ <u>6y²- x²</u>
Step-by-step explanation:
the difference of two squares is a squared number subtracted from another squared number, it has the general from Ax² - By²
We will check the options to find which shows a difference of squares.
1) 10y²- 4x²
The expression is similar to the general form, so the equation represents a difference of squares.
It can be factored as (√10 y + 2x )( √10 y - 2x)
2) 6y²- x²
The expression is similar to the general form, so the equation represents a difference of squares.
It can be factored as (√6y + x )( √6y - x)
3) 8x²−40x+25
The expression is not similar to the general form, so the equation does not represent a difference of squares.
4) 64x²-48x+9
The expression is not similar to the general form, so the equation does not represent a difference of squares.

Michael is x. Michelle is y.
x+y=27
x-5=y
Substitute y
x+(x-5)= 27
2x-5=27
2x=32
x=16
Plug in x value
(16)+y=27
y=11
Final answer: Michael-16, Michelle-11
Step-by-step explanation:
you did not provide any graphs but here's what I got.
Hope this helps!
This should mean that the machine will have a chance of choosing every number likely
