Answer:
impossible
Step-by-step explanation:
you need 3 different values including a side
Answer:
- 7, - 3, 1, 5
Step-by-step explanation:
Using the recursive rule and a₁ = - 7, then
a₂ = a₁ + 4 = - 7 + 4 = - 3
a₃ = a₂ + 4 = - 3 + 4 = 1
a₄ = a₃ + 4 = 1 + 4 = 5
The first four terms are - 7, - 3, 1, 5
The distance traveled by the balloon in every minute makes an arithmetic sequence with a first term equal to 40 ft and common difference equal to 20. The nth term of an arithmetic sequence is calculated by,
an = a1 + (n - 1) x d
Substituting,
an = 40 + (15 - 1) x 20 = 320
Thus, the answer is letter B. 320 feet.
Answer:
If you were to cut it in half (3.5 x 2)
The answer would be 7
Step-by-step explanation:
The first = x => the second = x + 4
Sum = x + (x+4) = 56
2x + 4 = 56
2x = 52
x = 26 - the first => the second = 30
