You can calculate the distance between two point using this fomula:
√(x_2-x_1)^2+(y_2-y_1)^2
If you insert you values you get:
√(4-5)^2+(-7-2)^2 = 9.06 = 9.1
Answer:
5DG=156 I think this is but I am not sure bro
Complementary is 90 degrees and supplementary 180 degrees
Answer:
70
Step-by-step explanation:
1) "20% of a number is 56"
Lets call this number "x".
0.20x = 56 (percents can become decimals by dividing 100)
2) 45% of the same number is 126
This will be the same number "x".
0.45x = 126
3) Divide by 0.45 (you can use a calculator)
0.45x / .45 = 126 / .45
x = 280
4) "25% of that number"
that number is x
25% is one-fourth of a number so
0.25x = 280/4
0.25x = 70
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.
