If ab plus bc equals ac then ac equals ab plus bc?
yes because ab plus bc is ac
A plus B equals AB?
No. A times B = AB
Given the equation AB plus CD equals 25 what conclusion can be drawn based on the Subtraction Property of Equality?
Ab = 25 CD
Ab plus c equals ab plus ac?
Difficult to tell when you cannot use parentheses. a*(b+c) or a(b+c) = ab + ac This is known as the distributive property of multiplication over addition.
How do you show that ab plus ab plus cc equals abc?
If, as is normal, ab represents a times b, etc then ab + ab + cc = 2ab + c2 which is generally not the same as abc.
