Recognize the differnce of 2 perfect squares

a²-b²=(a-b)(a+b)

so
\frac{x^2-y^2}{x-y}=\frac{(x-y)(x+y)}{x-y}=(\frac{x+y}{1})(\frac{x-y}{x-y})=(x+y)(1)=x+y

HELP PLEASE!!!!
TiliK225 [7]

When trying to solve a system of equations graphically, our focus is on identifying the coordinates of any point through which the graphs go. Look at the above graph: you'll see that the red and the blue graphs intersect at (0,2), and so (0,2) is a "solution" of that system of equations.

Here, we're asked to answer a different kind of question: "Is (2,0) a solution to the given system of equations?" Let's paraphrase that question: "Do both graphs go through (2,0)?" The answer: emphatically not. Neither graph goes through (2,0). Thus, (2,0) is not a solution to this system of equations.

Figure out this number pattern:<br>1,5,14,30,55
Amanda [17]

5 - 1 = 4 = 2^2

14 - 5 = 9 = 3^2

30 - 14 = 16 = 4^2

55 - 30 = 25 = 5^2

Start with 1, then add 2^2, 3^3, 4^2, 5^2, 6^2, etc.

Find the ratio of lengths 3 meters to 6 cm
jeka57 [31]

Step-by-step explanation:

Convert metre to centimetre

Recall: 1m = 100cm

That means,

3m = 3 * 100cm = 300cm

Now we compare them since they have the same unit.

300cm : 6cm

50 : 1

Answer = 50 : 1
