Answer:
20
Step-by-step explanation:
Use the distance equation to find the length of each side:
d = √((x₂ − x₁)² + (y₂ − y₁)²)
where (x₁, y₁) and (x₂, y₂) are the points (the order doesn't matter).
AB:
d = √((-2 − (-2))² + (-2 − 4)²)
d = 6
BC:
d = √((4 − (-2))² + (-2 − (-2))²)
d = 6
AC:
d = √((-2 − 4)² + (4 − (-2))²)
d = 6√2
So the perimeter is:
AB + BC + AC
6 + 6 + 6√2
≈ 20
Hope you mean converting to fractions. Hope this helps
Answer:
O lies on the perpendicular bisector of AB. ... Then, O' will lie on the perpendicular bisector PQ and RS. We know that, two lines cannot intersect at more than one point, So O' must coincide with O. Hence, there is one and only one circle passing through three non collinear points

Answer:
Mrs. Wong spend $545.76 on tiles.
Step-by-step explanation:
Mrs. Wong has 144 tiles that she is going to place on her square kitchen floor. If the tiles are $3.79 each, how much did Mrs. Wong spend on tile?
we are given
number of ties=144
cost of one tie=3.79 dollar
we have to find
total cost of 144 ties
for this we will multiply 144 by 3.79
multiplying 144 by 3.79 gives=144*3.79
it other words
one tile cost=$3.79
and for 144 ties cost
multiplying 144 on both sides
144 tiles cost=3.79*144=$545.76
To find area you multiply the height and width so which ever are the height and width out of those numbers you multiply them together
