Answer:
Option 3- Polygons
Step-by-step explanation:
Given : The faces of the polyhedron
To find : Which term describes the faces of the polyhedron?
1) Circles
2) Spheres
3) Polygons
4) line segments
Solution :
A polyhedron is a three-dimensional figure with flat polygonal faces, straight edges and sharp corners or vertices.
or a polyhedron is a closed, solid object whose surface is made up of a number of polygonal faces.
The definition itself clear that term describe the faces of the polyhedron is a polygons.
Therefore,Option 3 is correct.
Answer:
£40
Step-by-step explanation:
3+5=8
160÷8= 20
20× 5=100
20×3=60
100-60=40
Answer:
x= -15
Step-by-step explanation:
3x+10=2x-5
3(-15)+10=2(-15)-5
-45+10=-30-5
-35=-35
Each side of the angle is equal, that's how i knew the two were supposed to be equal. <3 Hope this helps!

Answer:
16x² + 64x + 64
Step-by-step explanation:
Given
A = 16x²
Increasing the sides by 2, substitute x = x + 2 into A
A = 16(x + 2)² ← expand factor using FOIL
= 16(x² + 4x + 4 ) ← distribute
= 16x² + 64x + 64
