Explain in your own words why (x + y)2 ≠ x2 + y2. Provide a numerical example to illustrate.

bekas [8.4K]

Im not sure if you wrote this wrong because (x+y)2 does equal x2+y2. An example would be if x equals 3 and y equals 4 (3+4)2=(3)2+(4)2 (7)2=6+8 14=14.

What is 575% written as a mixed number?

pav-90 [236]

Answer:

575% as a mixed number is $5\frac{3}{4}$

Explanation:

575% is equivalent to $\frac{575}{100}$ which is equal to 5.75

5.75 = 5 + 0.75

0.75 can be written as $\frac{75}{100}$ . This value can be simplified by dividing both the numerator and the denominator by 25. This would give us $\frac{3}{4}$
