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.
Answer:
3,327.9
Step-by-step explanation:
now: 1996.67
original: 3,327.9
1996.67/.6 = 3,327.9
10 is a common factor of 50 30 and 100. So is 2
Answer:
65
Step-by-step explanation:
Answer:
Melody have now $27.75
Step-by-step explanation:
We will proceed to solve the problem in parts so that it can be better understand
so
1) Originally Melody had $45
2) She spent $32.75 on a blouse
so
In this moment Melody has --------> $45-$32.75=$12.25
3) Her mother gave her $15.50
so
In this moment Melody has --------> $12.25+$15.50=$27.75
therefore
Melody have now $27.75
