Answer:

Correct answer is D(the intersection of lines N and M)

Step-by-step explanation:

we Know that circumcenter of a triangle is point at which the perpendicular bisectors of the sides of a triangle intersect and which is equidistant from the three vertices. In other words circumcenter of a triangle is the center of the circle which passes through the vertices of the triangle. It means, any side of the triangle will act as a chord of the circumcircle. Hence the circumcenter of a triangle must lie on the perpendicular bisectors of the sides. therefore the intersection of line N and M must be circumcenter of the triangle.

The perimeter of a rectangular pool is 180 yes. The length is 10yds more than the width. Find the length and the width of the po

White raven [17]

Answer:

Width: 85 yards

Length: 95 yards

Step-by-step explanation:

Ok, so we need to make an equation for this problem. Let's call the width, w. We know that the length is 10 more than the width, so we can call it w +10.

180 = w + w + 10

Now, i order to isolate the w's we need to subtract 10 from each side.

170 = 2w

Now, we just have to divide by 2 on both sides.

W = 85

So we now know that the width is 85 and because the length is 10 more, the length is 95 yds.

The commutative property of addition means the order of the addends doesn't matter; we get the same sum. In symbols

$a+b = b+a$

<span>11 + 7 = 7 + 11, choice B, is a good illustration of commutativity.

The next part asks us to use the commutative property. Looking at the choices, we see it's not the commutative property of addition we're to use, it's the commutative property of multiplication. Let's write that generally first:

</span> $ab = ba$

Applying that, <span>(4 + 7) * 3 = 3*(4+7), again choice B.
</span>
