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.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
