The coordinates of the vertices of a polygon are shown below

kakasveta [241]

Answer:

Option D.

Step-by-step explanation:

The given vertices of a polygon are D(-4,5),E(-1,5),F(1,2), and G(-1,-1).

Here, number of vertices is 4.

In heptagon, number of vertices = 7

In hexagon, number of vertices = 6

In octagon, number of vertices = 8

In quadrilateral, number of vertices = 4

Since the given polygon has 4 vertices, therefore it is a quadrilateral.

Hence, option D is correct.

Two numbers total 61 and have a difference of 37. find the two number

bulgar [2K]

Let x be the first number
Let y be the second number

x+y=61
x-y=37 --> x=37+y

(37+y)+y=61
37+2y=61
2y=61-37
2y=24
y=12

x+y=61
x+12=61
x=61-12
x=49

Therefore the numbers are 49 and 12

Hope I helped :)

A certain forest covers an area of 4000 km2. Suppose that each year this area decreases by 7%. What will the area be after 5 yea

Levart [38]

Answer:

2,600

Explanation:

Your first step is to find 7% of 4000 ( this is what it is decreasing by per year).
As a result you end up with 280.
Multiply 280 by 5.
1,400 should be your answer( amount of km decreasing after 5 years). This is a decreasing forest, so you subtract 4,000by 1,400.
