Which one is a "Associative Property Of Multiplication" A. z + 0 = z
B. 5(2r - 3) = 10r - 15
C. 4(5 + y) = (5 + y)4
D. 3(4r) = (3 *4)r
E. 3 + b = b + 3
F. 1(w) = w

The answer is D.

Step-by-step explanation:

First, we take the info we know. We know that this of multiplication. That means we can rule out A and E.

Now, we need to take the definition of the associative property. The associative property means that you keep the same numbers, variables, and operations, but you switch the grouping. This means that the answer is D. This is because, on both sides of the equation, we keep the same numbers variables and operations. However, on one side we have 4 grouped with r, and on the other, we have 3 grouped with 4. We switched our grouping but kept the expression. This means that our answer is D.

ask goog great chance of finding the solution there

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
