Answer:
The answer is B.
Step-by-step explanation:
You have to apply the area of triangle formula :
You know you are finished dividing when you can no longer simply & when you plug it back in to check the answer
Using the Pythagoras theorem
(sqrt 117)^2 = x^2 + 6^2
x^2 = sqrt117)^2 + 6^2
x^2 = 117 - 36 = 81
so x = 9 answer
Answer:
The sides are 24cm, 7cm, and 25cm
Step-by-step explanation:
3x+x-1+3x+1=56 <---- First we combine like terms (the 1's cancel out)
7x/7=56/7 <--- Divide by 7 to isolate the variable
x=8 <--- Now that we've solved for x we need to plug it back into each side
3(8)=24
(8)-1=7
3(8)+1=25
24+25+7=56 <---- Make sure it all adds up to 56
Hope this helps :)
Answer:
See explanation below.
Step-by-step explanation:
The first law of thermodynamic states that heat is a form of energy, and as such, is subject to the principle of conservation of energy (Energy is not destroyed or created but remains constant)
For example, when you put an ice cube in water, the ice will melt but the water will get colder, this is because the temperature between the ice cube and the water tends to an equilibrium and the total heat in the system remained the same during this time.
