Select the number sentence that illustrates the associative property of addition. a. (2 + 3) + 4 = (3 + 2) + 4 b. (2 × 3) × 4 = 2 × (3 × 4) c. (2 + 3) + 4 = 2 + (3 + 4) d. (2 × 3) + 4 = 2 + (3 × 4)

We know that

Associative property of addition:

now, we will verify each options

option-A:

we can see that

it does not satisfy right side

so, this is FALSE

option-B:

we can see that

this is multiplication

so, this is FALSE

option-C:

we can see that

both sides are similar to associative property of addition rule  

so, this is TRUE

option-D:

we can see that

this is multiplication

so, this is FALSE

step-by-step explanation:

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
