Answer:
a = 
- b
Step-by-step explanation:
Given
c(a + b) - d = f ( add d to both sides )
c(a + b) = f + d ( divide both sides by the multiplier c )
a + b = ( subtract b from both sides )
a = - b
Answer:10
Step-by-step explanation:
you need to do math
This question is just a question targeted towards puzzling the solver. It is infact a very easy problem. In the given question the information's provided should be very minutely watched. First information says that there is an unknown number. The problem revolves around this unknown number and various information's show that this number is always connected with the majority information's provided.
Let us assume the unknown number = x
Then
2x -4 = x - 10
2x - x = - 10 + 4
x = - 6
So the unknown number is -6.
Answer:
2340 degrees
Step-by-step explanation:
Each triangle has an angle sum of 180 degrees, therefore the sum of interior angles of 15-gon will be 13×180=2340
Equation: 4 + 4x + x²
Maxima: No maximum value from said equation
Minima: x = -2 since that is the only critical point in the equation
