A. Both triangles equal 50 and 10x5 is 50. Therefore, y=5.
Answer:
6mm
Step-by-step explanation:
B is x.
15 IS HYPOTENUS.
Therefore b is15-9
Rewrite it in the form a^2 - b^2, where a = 2x and b = 5
(2x)^2 - 5^2
Use the Difference o Squares: a^2 - b^2 = (a + b)(a - b)
<u>(2x + 5)(2x - 5) </u>
in the urban ecosystem, the air is always is so much pollute, the waters too are always so much polluted hence not so much good for non human life. but in the undeveloped forest ecosystem, the air is so much fresh, the environment and the waters too hence find it better in the place.
