Answer:
aₙ= 3n+1
Step-by-step explanation:
4 ,1 -2, -5 ,-8
AP with a₁=4 and d= -3
----------------
aₙ= 4+3*(n-1)= 4+3n-3= 3n+1
aₙ= 3n+1
The average was 34 yards because 35+30+37= 102 then you do 102/3
X=(6+3\sqrt(19))/(5),(6-3\sqrt(19))/(5)
x=3.81533936,-1.41533936
Answer:
collect like terms x=5-4=1
Because the angles are vertical angles, they are equal.
Set the equations equal to each other:
5x+100 = 3x+112
Subtract 100 from 112:
5x = 3x+12
Subtract 3x from 5x:
2x = 12
Divide 12 by 2:
x = 6
x is equal to 6
