Answer:

20

Step-by-step explanation:

-3y+12=-48 1) Subtract 12 from both sides

-12 -12

2) <u>-3y</u>=-<u>60</u> 2) Divide both sides by -3

-3 -3

3) y=20

-3y+12=-48
Move 12 to the other side of the equation by subtracting and cancelling out 12
-3y=-36
Then divide by -3 to both sides to get Y by itself
Y=12

Find the area of the polygon with vertices (1, 2) (1, -5) (5, -5) (5,2)
Svetradugi [14.3K]

Answer:

28 square units

Step-by-step explanation:

These vertices are written in the form of their x and y coordinates. Let

A=(1,2) ; B =(1,-5) ; C =(5, -5) ; D=(5,2)

The x points are 1, 1, 5, 5

The y points are 2,-5, -5, 2

The x extremes range from 1 to 5. The length  in-between is 5-1 = 4

The y extremes range from -5 to 2. The length  in-between is 2-(-5) = 7

Area of the polygon enclosed by the coordinates

   = 4 x 7 = 28 square units
