Answer:


Step-by-step explanation:
The vertices of quadrilateral ABCD are A(1,0) B(5,0) C (7,2) D(3,2).
The slope of side AB is

The slope of side BC is

The slope of side CD is

The slope of AD is



We see that the opposite sides of the quadrilateral ABCD are equal.
Hence the quadrilateral is a parallelogram
Answer:
.754
Step-by-step explanation:
Percentage is based off of 1 or 100% which is equal to 1. So 50% or half of both 100% and 1 would be translated as .5 and as the percentage becomes more accurate or lengthy you add to the decimal so 53% is .53 and 53.4% is .534
Y/2=?
y=4
4/2=2
so y divided by 2 is 2.
Have a nice day!!~~~ ^-^
Please see attached graphic for answer
21

half the height is 3
a=7
b=x
3(7+x)=84
21+3x=84
place the like terms on one side
84-21=3x
63=3x
x=21
