Answer:
-4.25
Step-by-step explanation:
The given number is 4.25 and we have to find the opposite of this number.
Opposite of a number is also known as additive inverse and it is defined as "if the sum of two numbers is zero then two numbers are opposite or additive inverse of each other"
For example, if x is a number then its opposite is -x.
and hence, x + (-x) = 0
Using this fact, we can conclude that the opposite of 4.25 is -4.25 because
4.25 + (-4.25)
= 4.25 - 4.25
=0

Answer:
The perimeter of the polygon is 
Step-by-step explanation:
we know that
The perimeter is the sum of the length sides of the polygon
In this problem
P=XY+YZ+XZ
the formula to calculate the distance between two points is equal to
step 1
Find the distance XY
we have
X(−1, 3), Y(3, 0)
substitute
step 2
Find the distance YZ
we have
Y(3, 0), Z(−1,−2)
substitute
step 3
Find the distance XZ
we have
X(−1, 3), Z(−1,−2)
substitute
step 4
Find the perimeter
P=XY+YZ+XZ
