Answer:

n = (-4)

Step-by-step explanation:

Firstly expand the bracket

;2[3(1 - n) -2(1+n)]

;2[ 3 - 3n - 2 - 2n ]

;2[ -5n + 1 ]

; -10n + 2

then go back to the question and substitute the bracket with the simplified form above,

; 7n - 10n + 2 = 14

; -3n = 14 - 2

; -3n = 12...then divide both sides by (-3)

;Hence... n = (-4)

Determine the value of w and x in the figure below. (Thanks for the help I really appreciate it!)​
storchak [24]
Triangle HAM looks like an isosceles triangle, and we know that in an isosceles triangle 2 of the angles are the same.

so :
180 - 106 = 74 ( sum of the other 2 angles )
74/2 = 37 ( sum of angle HMA / HAM )

angles on a straight line add up to 180.
180-37=143 ( angle x )

since triangle YMH is also an isosceles,
180-37=143
143/2=71.5 ( angle w )
