12. SHORT RESPONSE For each expression, explain how to use the properties of addition and multiplication to simplify the expression with the easiest
computation possible. Show your work and name the properties you used.
Part A 47 x 38 + 47 x 62
Part B 752 + (467 + 248)

Pls! does anybody know a shortcut for answering these types of questions in the future?

Find the value of x for which the lines are parallel.

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
