Not sure what this means plz ? 1. which property is illustrateda. (m+7.3)+4.1=m+(7.3+4.1)2. 12x+4y+0=12x+4y3. (3r)(2s=(2s)(3r)these are the same question plz

Step-by-step explanation:

a.(m+7.3)+4.1=m+(7.3+4.1)  - Associative property of addition

The addition or multiplication of a several

numbers is the same regardless of how the numbers are grouped. The

associative property will always involve 3 or more numbers. The

parenthesis groups the terms that are considered one unit.

2. 12x+4y+0=12x+4y

Additive Identity Property

This means that you can add 0 to any number...  and it keeps its identity!  The number stays the same!

3.

(3r)(2s=(2s)(3r)

Commutative property of multiplication

The commutative property of multiplication states that two numbers can be multiplied in either order.

answer: y=4000x+14000

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
