Step-by-step explanation:

Side of the octagon

An octagon has 8 sides. Each side is 2a + 1 units.

8(2a + 1)

= 16a + 8

Given,

  • Side of the octagon = ( 2a + 1 ) units

» Perimeter means total length of its boundary.

→ Octagon has 8 sides.

So,

→ Perimeter of Octagon = Length of 8 sides

→ Perimeter of Octagon = 8 ( 2a + 1 ) units

→ Perimeter of Octagon = 16a + 8 units

Therefore,

  • Perimeter of the octagon is \bf 16a + 8 units.

On a coordinate plane, triangle A B C has points (negative 3, negative 1), (negative 2, negative 3), (1, negative 1) and is refl
andreev551 [17]

Answer:

A' = (-3, 3)

Step-by-step explanation:

If the points are as follows:

A = (-3, -1)

B = (-2, -3)

C = (1, -1)

When reflecting across a y axis the x values remain the same.

When reflecting across y = 1 the y values will remain equal distant from y = 1.

A' = (-3, 3) y value = |-1 - 1| = 2 + 1 = 3

B' = (-2, 5) y value = |-3 - 1| = 4 + 1 = 5

C' = (1, 3) y value = |-1 - 1| = 2 + 1 = 3
