Hello from MrBillDoesMath!
Answer: Commutative Property
Discussion: The commutative property, generally, indicates that
a + b = b + a for any number. In other words one can "flip around" the values being added and no change the result..
Step 4: 5y + 10 + 6y
Step 5: 5y + 6y + 10
IN this problem the commutative property is applied to the boldfaced values shown above.

Can u plz be a lil more pacific so i can help
Answer: C) SAS is correct
Check out the diagram below.
We're given BA = BC as shown in red.
The congruent angles are shown in blue. The larger angle is bisected into smaller equal halves.
The red segments are congruent by the reflexive property.
The angles mentioned are between the sides mentioned, so that's why we can use SAS.
<span>The rectangle is 17 meters wide and 31 meters long. To solve this problem, first work out the equation for the length of the rectangle. Using the information given, we find that length (L) is given by L=2W-3. Next we setup the formula for the area of a rectangle, A=(W)(L). We are told that the area is 527 sq. meters, so our equation is 527=(W)(L). We also know that L=2W-3, so we can plug that into the equation for area as well which gives us 527=W(2W-3), which can be written 0=2(W^2)-3W-527. We now need to solve this equation for W.
Factoring the left side we get, 0=(W-17)(2W+31). Thus, either (W-17)=0 or (2W+31)=0 must equal zero. Solving these two equations, we get W=17 or W=-15.5.
Since we are looking for the width (which is a length), we know it cannot be negative and therefore the width must be 17 meters.
Now that we know the width, we can plug W=17 back into the equation for length (L=2W-3). Doing this give us L=2(17)-3 which is equal to 31. Thus the length is 31 meters.</span>
