To divide by a fraction, multiply by the reciprocal of that fraction.
1/3 • 5/1 or 1/3 • 5
Calculate the product straight across.
1/3 • 5/1 = 5/3
Answer:
Step-by-step explanation:
Area = 1/2 * 2b * (5b - 7)
Area = 1/2 * 2b * (5b - 7) = 24
b * (5b - 7) = 24
5b^2 - 7b = 24
5b^2 - 7b - 24= 0
(b- 3 )(5b + 8) = 0
b = 3 This the only solution that works. b can't be minus
The base is 2b or 2 * 3 = 6
Answer:
64
Step-by-step explanation:
Note that each new term of this geometric sequence is 2x the previous term.
If the sequence starts off as 2, 4, 8, 16, 32 ... , then the next term is 2(32) = 64.
