Answer:
-21
Step-by-step explanation:
if for s(n) = -3-3n
then s(6) = -3-3*6 = -3-18 = -21
4.133 kilometers
2.063 + 2.07 = 4.133
The value of x is 30; hence 4x is equal to 120. That is because the sum of the angles of a triangle is 180. So, add x, x and 4x together, you get 6x. Divide 180 by 6, you get 30. Hope this helped!
