What property or properties prove (2x)(3y)(4z)=24xyz

Associative property of multiplication

Step-by-step explanation:

The associative property of multiplication.

The associative property says that the way in which factors are grouped in a multiplication problem does not change the product.

Lets solve the given expression.

(2x)(3y)(4z)=24xyz

According to associative property of multiplication you can write it as 2x(3y*4z)=(2x*3y)4z

Both the sides will give the same answer regardless of their order.

2x(12yz) =(6xy)4z

24xyz = 24xyz

Thus the answer is associative property of multiplication

answer: b.36 feet

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
