Answer:
let second side be x
then first side = x-13
third side= x+1
now
perimeter of triangle = 45
x-13+x+x+1=45
3x=57
x=19
first side = x-13= 19-13=6
third side= x+1=19+1=20
Step-by-step explanation:
Differentiate:
-5×2(xe^x^2)y-5e^x^2dy/dx=1
-5e^x^2(2xy+y´)=1
When x=-5, y=0:
-5e²⁵y´=1, so y´(-5)=-eˉ²⁵/5
