Step-by-step explanation:
perimeter of a rectangle is 2(length + width)
p= 2[ (2x -3) + (x+2 )]
combines like terms
p = 2 ( 3x -1 )
p = 6x -2

Step-by-step explanation:
X = 6.
The angle bisector theorem tells us that the ratio of the lengths of the line segments on the side the bisector intersects is the same as the ratio of the lengths of the sides adjacent to the intersected side. So using the theorem and the diagram, we can create this equation, and then solve for x.
(4x+1)/15 = 5/3
15*(4x+1)/15 = 15*5/3
4x+1 = 5*5
4x+1 = 25
4x+1-1 = 25-1
4x = 24
4x/4 = 24/4
x = 6

Step-by-step explanation:
move the decimal two places to the right (add or take away the zero)
Answer:
6
Step-by-step explanation:
The sum of the exterior angles of any polygon = 360°
Thus the sum of the interior angles = 2 × 360° = 720°
The sum of the interior angles of a polygon = 180° (n - 2), hence
180(n - 2) = 720 ← divide both sides by 180
n - 2 = 4 ← add 2 to both sides
n = 6
The polygon has 6 sides
