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)
Answer:
c.2
Step-by-step explanation:
5(x+4)<32
5(2+4)<32
10+20<30
The common difference is essentially what u need to add to one number in the sequence to get the next
So previous number + common difference = next number after that
The common difference would be -8
Answer:
A. 30
Step-by-step explanation:
sin theta = opposite side / hypotenuse
sin B = 8/16
sin B = 1/2
Take the arcsin of each side
arcsin sin(B) = arcsin (1/2)
B = arcsin (1/2)
B = 30
