The given question is wrong.
Question:
Which expression is equivalent to the given expression using commutative property of addition? 2(x + b) + 3(xa).
Answer:
Option C:
3(xa) + 2(x + b)
Solution:
Given expression is 2(x + b) + 3(xa).
To find the equivalent expression using commutative property of addition.
Let us first define the commutative property of addition.
a + b = b + a
You can add in any order.
Now, write the given expression using commutative property.
2(x + b) + 3(xa) = 3(xa) + 2(x + b)
Option C is the correct answer.
Hence 3(xa) + 2(x + b) equivalent expression using commutative property of addition.
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
