Which equation applies the associative property of multiplication?

−6/5−(5/3−1/4)=(−6/5−5/3)−1/4
(−9/4⋅3/2)⋅(6/3⋅5/7)=−9/4⋅(3/2⋅6/3) ⋅5/7
(−1/2⋅4/7)+(−1/2⋅2/3)=−1/2⋅(4/7+2/3 )
8/9⋅7/4⋅(−5/8)=8/9⋅(−5/8)⋅7/4

Brittany has designed four different birdcages, each with the same volume: a square pyramid, a cylinder, a cone, and a sphere. the zoo wants to use one of brittany’s designs but plans to change the volume of the cage. find the design change that would result in the birdcage with the greatest volume. a.) increase the area of the base of the square pyramid by a factor of ten. b.) increase the height of the cylinder by a factor of ten. c.) increase the radius of the cone by a factor of ten. d.) increase the radius of a sphere by a factor of ten.

Astudent solves the equation for v. start with the original equation. use the square root property. use the division property of equality. use the multiplication property of equality. simplify. which statement explains how to correct the error that was made? the square root property must be applied after all other properties of equality are applied. the multiplication property of equality should have been applied before the division property of equality. the division property of equality should have been applied to move the fraction to the other side of the equation. the square root property should have been applied to both complete sides of the equation instead of to select variables.
