Why the area and the perimeter are not both multiplied by the same factor.
lina2011 [118]

Answer:

Step-by-step explanation:

It might be the length of one of the sides of a polygon (a figure with straight sides) or the radius of a circle. ... You can find the perimeter of a regular octagon (8-sided figure with equal sides) by multiplying the length of one of the sides by 8. The area of a figure is the measure of how large its surface is.

Answer:

-3<y<=3 or B

Step-by-step explanation:

so the answer would be -3<x<=3

Graph the system of equations on graph paper.
MrRa [10]
Ths system of equations is

<span>8x+6y=48 ..............>y = 48/6 -8x/6
2x−3y=−6 ..............>y = 6/3 + 2x/3

If we use a graphic tool, we can easily check the solution, 
which is (x,y) = (3,4)

The ordered pair lies in Quadrant I
