Answer:
circle P has a circumference of 800mm which is equal to 80cm
circle Q is 200cm
circle R is 4m which is equal to 400cm
You will get the sum of the distances by placing the figures under one measurement that is meters
And so add the figures in cm(200+400+80) and get 680
Then convert this to meters and get 6.8m
Hence your answer is C
First: (X+3)(x+3) foil it.
Then distribute the 3x among the values and combine like terms
Answer:

Step-by-step explanation:
If a given variable varies inversely with another variable, an increase in the value of the given variable would cause a corresponding decrease in the value of the other variable. Also, a decrease in the value of the given variable would cause a corresponding increase in the value of the other variable.
If y varies inversely with x, we would introduce a cost of variation, k so that the expression becomes
y = k/x
When y = 0.25, x = 8
Substituting into the expression above, it becomes
0.25 = k/8
k = 0.25 × 8
k = 2
The inverse variation function is
y = 2/x
