Which example illustrates the associative property for addition?

(3 x 7) + 8 = 3+ (7 x 8) = (3x 8) + 7

(3+7) x 8 = 3 x (7 + 8) = (3 + 8) x 7

(3+ 7) + 8 = 3x (7 x 8) = (3 + 8) + 7

(3 + 7) + 8 = 3 + (7 + 8) = (3 + 8) + 7

Answer:

(3 + 7) + 8 = 3 + (7 + 8) = (3 + 8) + 7

Explanation:

The equations for associative property for addition are:

(a + b) + c = a + (b + c)

So, (3 + 7) + 8 = 3 + (7 + 8) = (3 + 8) + 7 is the answer!

Answer:

The answer is that the third example illustrates the associative property for addition. The associative property states that the order in which numbers are added does not affect the result. In other words, (a + b) + c = a + (b + c) for all numbers a, b, and c.

The third example follows this pattern:

(3 + 7) + 8 = 3 + (7 + 8) = (3 + 8) + 7

The other examples do not follow this pattern, so they do not illustrate the associative property for addition.

The first example illustrates the associative property for multiplication, which states that the order in which numbers are multiplied does not affect the result. In other words, (a x b) x c = a x (b x c) for all numbers a, b, and c.

The second example is not a valid mathematical expression, as it attempts to add a number and a product.
