Length of KL is 17 units
Given that;
L is mid point of KM
KL = 2x - 3
LM = x + 7
Find:
Length of KL
Computation:
We know that,
L is mid point of KM
So,
KL = LM
2x - 3 = x + 7
2x - x = 7 + 3
x = 10
So,
Length of KL = 2x - 3
Length of KL = 2(10) - 3
Length of KL = 20 - 3
Length of KL = 17 units

Answer:
The value of account after 8 years is $8580
Step-by-step explanation:
Given in question as :
The principal that invested in an account = $6,000
The annual interest rate compounded quarterly = 4.5%
Time period = 8 years
Now from compound Interest method for quarterly .
Amount = Principal 
Or,Amount = $6,000 
Or, Amount = $6,000 (1.430)
∴ Amount = $8580
Hence the value of account after 8 years is $8580 Answer
=7(18x9+4)
=7(162+4)
=7x166
=1162
answer=1162
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.

Answer:
$135
Step-by-step explanation:
6.75 x 5 = 33.75 (to find the amount of money he earned each night)
33.75 x 4 = 135 (amount earned per night by the number of nights worked)
$135 (final answer)
