I believe that the answer is -18.
Hi there!
We are asked to find the correct factored form of n² - 25. Immediately, we can see that 25 has a perfect square root, 5. Now, we can rewrite the expression into n² - 5². Finally, using the difference of squares rule, we can derive the equation (n + 5)(n - 5). Therefore, the answer is (n + 5)(n - 5). Hope this helped!
When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases. Part of the wave travels faster for longer causing the wave to turn. The wave is slower but the wavelength is shorter meaning frequency remains the same
the answer is 0.56, because there’s 56 shades squares.
Explanation: there’s 100 squares, 56 are shaded 56/100.
Answer:
Hypotenuse = 11.4 cm
Step-by-step explanation:
Hypotenuse ² = opposite ² + adjacent ²
Opposite = 7 cm
Adjacent = 9 cm
Hypotenuse ² = opposite ² + adjacent ²
= 7² + 9²
= 49 + 81
Hypotenuse ² = 130
Hypotenuse = √130
= 11.40
Hypotenuse = 11.4 cm
