Answer:
x = 24°
Step-by-step explanation:
To find 'x', the Alternate Exterior angle postulate will need to be used.
'4x + 9' and '2x + 27' are alternate exterior angles. Therefore, they must sum up to 180.
180 = 4x + 9 + 2x + 27
Combine like terms:
180 = 6x + 36
144 = 6x
x = 24°
Answer:
median= 6.5
Step-by-step explanation:
6= 2+5+x+1+x+2+7+9/6
summing up the values
26+2x=36
collecting like terms,
2x=10
divide both sides by 2
x= 5
5+1=6
5+2=7
so the numbers are 2 5 6 7 7 and 9
the median = 6+7/2
= 6.5
Answer: 2x(x+2)−(x+2)
Step-by-step explanation:
Factor out common terms in the first two terms, then in the last two terms.
2x(x+2)−(x+2)
Factor out the common term x+2.
(x+2)(2x−1)
