Step-by-step explanation:
Answer:
A. The 2 groups could be quadrilateral and triangles.
quadrilateral-1,2,,6,7
Triangles-3,4,5,8,9
B.You could also sort them into shapes with 4 sides and shapes with 3 sides.
4 sides-1,2,,6,7
3 sides--3,4,5,8,9
C. They are all polygons becuase they all have 3 or more striaght sides and they all are closed shapes.
Step-by-step explanation:
Answer: length = 13
Width = 22
Step-by-step explanation:
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(length × width)
The length of the rectangle is represented by (x+3) and the width is represented by (3x-8). If the perimeter of a rectangle is 70, it means that
2[(3x - 8) + (x + 3)] = 70
Dividing both sides of the equation by 2, it becomes
3x - 8 + x + 3 = 35
3x + x - 8 + 3 = 35
4x - 5 = 35
4x = 35 + 5 = 40
x = 40/4
x = 10
Length = x + 3 = 10 + 3
Length = 13
Width = 3x - 8 = 3 × 10 - 8
Width = 22
Use the slope formula
Plug in the appropriate cords into the formula.
The slope of the line is -9/14.
