Answer:
i think its 12 :)
Step-by-step explanation:
20 + 48 = 68
180 - 68 = 112
20 + 48 + 112 = 18 (a full triangle!)
The expression we have is:

And we are given some values for x and y:

The first step will be to substitute the given values into the expression:

The next step is to solve 4^2 which is equal to 16:

And then we solve the multiplications, 2(2)(4) is equal to 16 and (2)(16) is equal to 32:

Solving this final multiplication we get the result:

Answer: 512
Answer:
The mass of sun is 333333.33 times greater than the mass of earth
Step-by-step explanation:
Given as :
The mass of the sun =
kg
The mass of earth =
kg.
Let The mass of sun is x times greater than the mass of earth
i.e The mass of sun = x × The mass of earth
or,
kg =
kg × The mass of earth
Or, x = 
Or, x = 
∴ x = 333333.33
So, The mass of sun = 333333.33 × The mass of earth
Hence, The mass of sun is 333333.33 times greater than the mass of earth Answer
