In the two triangles, all the three sides are congruent to the corresponding sides of the other triangle. And in such case, the criteria used for congruency is Side Side Side or SSS .
So the correct option is the first option .
Answer: She would have to practice for 3/4 of an hour left to reach her goal
Answer:
x = 0 and x = -2 are solutions of the given rational equation.
Step-by-step explanation:
We must solve the following rational equation:
Now we present the procedure:
1) Given
2) 
Compatibility with multiplication/Existence of the multiplicative inverse/Definition of division/Modulative property.
3) 
Distributive property/
4) 
Compatibility with addition/Existence of the additive inverse/Modulative property/Reflexive property
5) 
Distributive property/
6) 
Result
Now we check the rational equation with each root:
x = 0
x = 0 is a solution of the rational equation.
x = -2
x = -2 is a solution of the rational equation.
Y = t*e^(-t/2)
y' = t' [e^(-t/2)] + t [e^(-t/2)]' = e^(-t/2) + t[e^(-t/2)][-1/2]=
y' = [e^(-t/2)] [1 - t/2] = (1/2)[e^(-t/2)] [2 - t] = - (1/2) [e^-t/2)] [t -2]

4 : 6
60.
60 / 4 = 15
60 / 6 = 10.
15+ 10 = 25 times.
