Answer:
6x - 11 feet
Step-by-step explanation:
Dale is standing (2x + 7) feet height from the base of the tower.
And the tower is given to be (8x - 4)feet tall.
We have to find the distance between Dale and the top of the tower.
Now, the distance between dale and the top of the tower = height of the tower - height of Dale = (8x - 4) - (2x + 7) = (6x - 11) feet. (Answer)
Answer:
I dont really understand the question but I think its -7.
Answer:
115
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 7 - 1 = 13 - 7 = 19 - 13 = 25 - 19 = 6
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 1 and d = 6 , thus
a₂₀ = 1 + (19 × 6) = 1 + 114 = 115
