Ivana wrote the equation \( 50+30=10(5+30) \) to match this statement.
The sum of 50 and 30 is equal to the greatest common factor of 50 and 30 times the sum of 2 numbers.
Is Ivana correct? Why or why not?
A Ivana is correct because 10 is the greatest common factor of 50 and 30 .
B
Ivana is not correct, because 50 and 30 have a common factor of 5 , so 10 is not the greatest common factor of 50 and 30 .
C Ivana is not correct, because \( 50+30 \) is not equal to \( 10 \times 35 \).
D. Ivana is correet because \( 10 \times 5 \quad 50 \), and when 30 is added, both sides of the equation equal 80 .
