Answer:
Use the distance formula to find the length of each side, and then add the lengths.
Step-by-step explanation:
We are given the vertices of a quadrilateral in the coordinate plane.
We have to find the perimeter of the figure.
For doing so, we have to find the length of all the sides of a quadrilateral
The length of a line segment joining points (x1,y1) and (x2,y2) is given by the distance formula: 
after finding length of all the sides, we add the length of each side to get the perimeter.
Hence, the correct option is:
Use the distance formula to find the length of each side, and then add the lengths.
Answer:
One student costs $3.75
Step-by-step explanation:
Unit rate is how much it is for 1 item. In this case, we want to know the cost for 1 student.
$30/8 students ... if it is $30/8 students, you can divide by 8 to find out how much it is for one student.
$30/8 = $3.75
Answer:
V= 78.54
Step-by-step explanation:
X² - 3x - 4 = 0
Reverse FOIL method . . .
(x - 4)(x + 1) = 0
one of the paranthesis has to be equal to zero if the other is not . . .
x - 4 = 0
<u><em>x = 4</em></u>
x + 1 = 0
<u><em>x = -1</em></u>
Answer:
15,000
Step-by-step explanation:
10x10x30
10x10=100
100x30=3,000
50x20x12
50x20=1,000
1,000x12=12,000
3,000+12,000=15,000
