Answer:
hope this answer will help u.
Step-by-step explanation:
<em>( 5x + 3y )² - ( 5x - 3y )² - 60xy</em>
<em>= ( 25x² + 30xy + 9y²) - ( 25x² - 30xy + 9y² ) - 60xy</em>
<em>= 25x² + 30xy +9y² - 25x² + 30xy - 9y² - 60xy</em>
<em>= 60xy - 60xy</em>
<em>= 0</em>
1/6x >= 5
6 (1/6x)>=6 (5)
x>=30
35,32,40
Use the Pythagorean theorem:
Let x = the height.
2^2 + x^2 = 7.5^2
Simplify:
4 + x^2 = 56.25
Subtract 4 from both sides:
x^2 = 52.25
Take the square root of both sides:
x = 7.2284 m Round the answer as needed.
