let the unknown side be x , so we have :
25^2 = 20^2 + x^2
625 = 400 + x^2
x^2 = 625 - 400
x^2 = 225
x = √225
x = 15

Answer:
LM=11
Step-by-step explanation:
LN= ML+MN
4x+9=(2x+7)+(3x)
4x+9=5x+7
5x-4x= 9-7
x=2
LM=2x+7 =2(2)+7=4+7=11
X = -b/2a, given that the function is in the form y = ax^2 + bx + c
