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:
Step-by-step explanation:
GIVEN: A square with base 
, a circle that perfectly fits inside square.
TO FIND: Approximate area of circle.
SOLUTION:
Consider the figure attached.
let the radius of circle be 
radius of circle 
Area of circle 
Hence the area of circle that perfectly fits inside the square is
y=1.5x+3
Observing the graph
Let,
A(0,3) -----> this point is the y-intercept of the line
B(2,6)
We know that
The equation of the line into slope intercept form is equal to
y = mx + c
where
m is the slope
b is the y-coordinate of the y-intercept
In this problem
b=3
Find the slope of the line m
The formula to calculate the slope between two points is equal to
m = y2-y1 / x2-x1
substitute the values
m = 6-3 / 2-0
m = 3/2
m = 1.5
The equation of the line is
y= 1.5x+3

The answer is the last one. If and only if means that both things are the result of one another. for example... If it's valentines day, it is February but if it's February, it's not necessarily Valentines day.
