Answer:
210 m
Step-by-step explanation:
Perimeter is the distance around the outside of a two-dimensional shape.
Area is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.
Christen ran around the soccer field, so she ran around the perimeter.
We can find the perimeter by adding all of the side lengths.
Perimeter=60 m+45 m+60 m+45 m
Christen ran 210m.
Answer:
The correct option is subset.
Step-by-step explanation:
If all elements of set A are also elements of set B, then set A is a(n) <u>subset</u> of set B
According to the definition of subset, A set A is a subset of another set B if all elements of the set A are elements of the set B. In other words, the set A is contained inside the set B. It is denoted by A⊆B.
For example:
A={1,2,3} B={1,2,3,4}
In this example A is a subset of B because all the elements of A are elements of set B but set B has some extra element. Therefore A is a subset of B
Therefore according to the given explanation the correct option would be subset....
Answer:
x=1
Step-by-step explanation:
2x+6=8
= 2x=2
= x=1
Answer:
8 and 3/10 < 8 and 7/10
Step-by-step explanation:
7/10 is more than 3/10
3x+x=y
3(-3)+(-3)=y
-9-3=y
-12=y
Therefore the value of x3+x is -12
