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>
The value of x is given by the pythagoras theorem
X^2 = 17^2 - 15^2
X^2 = 289-225
X^2 = 64
X = sqrt64
X= 8cm
