Answer: 25
Step-by-step explanation: Your welcome
Im not sure but I think could be
3x=0
Given that I no not see any explanation in the previos answer, I think you can benefit of this.
Exothermic refers only to the fact that the reaction releases energy in the form of heat when occurs. So, the enthalpy is higher at start and lower and the end.
Seen in this way, you can deduct that the change in enthalpy is negative, which is what the third option says.
Answer:
Step-by-step explanation:
lets have one side =a
P=3a+a+(17+a)=52
P=5a+17=52
5a=52-17
5a=35
a=7
second side=21
third side=24
Answer:
The function concerning the evolution of the value of the first car is exponential and the one concerrning the value of the second car is linear
Step-by-step explanation:
1st car's drop in value ( not considering the second hand type of drop):
1.4500$
2.4050$
3.3645$
2nd car's value is dropping 3000$ every year so the function is f(n)=45000-3000n, n- number of years
