Answer:
Perimeter of the figure = 24 m.
Step-by-step explanation:
The given figure is a square of side 6 m in which a rectangle of length 4 m and width 2 m is cut at the corner.
Therefore, the missing sides are 6-4 = 2 m and 6-2 = 4 m.
Hence, the perimeter of the figure = 6 + 6 + 2 + 2 + 4 + 4 = 24 m.
The volume of the prism given its dimensions is equal to 160 cubic units.
<h3>What is the volume of the
prism?</h3>
The given prism is made up of two prisms. The volume of the prism is the volume of the two shapes.
- One of the prisms have the dimensions: 4 x 4 x 5.
Volume = 80
- The other prism has the dimensions: 8 x 2 x 5.
Volume = 80
Volume of the prism = 80 x 2 = 160 cubic units.

Answer:
8
Step-by-step explanation:
0 = –x^2 + 4x – 2
This is of the form
ax^2 +bx +c
a = -1 b = 4 x = -2
The discriminant is
b^2 -4ac
4^2 - 4(-1)(-2)
16 - 8
