9x - 24 + 4x = -24 + 14x - x
13x - 24 = 13x - 24
0 = 0
Answer is All real numbers
The combination expression that demonstrates how the 20 is calculated using the combination pattern is 6C3
<h3>Permutation and Combination</h3>
While combination has to do with selection, permutation has to do with arrangement.
According to the combination rule
nCr = n!/(n-r)!r!
The expression that gives the result of 20 is expressed below;
6C3 = 6!/(6-3)!3!
6C3 = 6!/3!3!
6C3 = 6!/6*6
6C3 = 720/36
6C3 =20
Hence the combination expression that demonstrates how the 20 is calculated using the combination pattern is 6C3

Answer:
degree 5
Step-by-step explanation:
the degree of a polynomial is determined by the term with the largest exponent and is the value of the exponent.
is the term with the largest exponent of 5
degree of polynomial is 5
Answer:
DF = 14
Step-by-step explanation:
Andrew was wrong in the assumption that DE = EF
Segments of tangents to a circle from the same external point are congruent
That is
EF = FG = 8
Then
DF = DE + EF = 6 + 8 = 14
2x² + 3x + 1
2x² + 2x + x + 1
(2x + 1)(x + 1)
