I think its 7x since x represents the hours she worked. So lets say that she worked for 5 hours this day. It would be 5*7 which is $35. So it is 7x and if there is any choices you might say it as well so we can help you better
Answer:
1: she used the wrong formula
2: 36cubic feet
3: the strategy: knowing that to find the volume of a rectagle is l*w*h and subtituting in the correct numbers
Step-by-step explanation:
1: to find the volume of a rectangle is height*width*length
2: you multiply 6*5*1.2 and you should get 36 and sice you are finding volume it is cubic and the measurment
If the number of the edges of the polyhedron is 14 and the vertices are 9. Then the number of the faces of the polyhedron is 7.
<h3>What is a
polyhedron?</h3>
A polyhedron is a solid made composed of polygons in three dimensions. It has vertices, flat faces, and straight edges.
We know the Euler's formula
F + V - E = 2,
where, F = number of faces, V = number of vertices, and E = number of edges
Edges: 14
Vertices: 9
F + 9 - 14 = 2
F = 14 + 2 - 9
F = 16 - 9
F = 7
Then the number of the faces of the polyhedron is 7.
