Step-by-step explanation:
I believe this is right, if not feel free to critique me and I will fix it. I'm sorry in advance if it is incorrect.
Since 7 yd is 21 ft you will have to
add 15 ft to 21 ft (36 ft)
and then divide by two
your answer is 18 ft
55, 50, 45, 40, 35,…
- 5 - 5 - 5 - 5
The common difference between the terms of the arithmetic sequence is -5, making the answer D.
a(n) = a₁ + d(n - 1)
a(n) = 55 - 5(n - 1)
a(n) = 55 - 5(n) + 5(1)
a(n) = 55 - 5n + 5
a(n) = -5n + 55 + 5
a(n) = -5n + 60
Plug them in
(5)(2)[(4(3)-2(2)]
Now you solve
10(12-4)
Distribute
120-40
