1. You will need 3 packs of tulips and 2 packs of geraniums.
2. You should have 18 flowers of each kind
Explanation:
1. To find the number of packets, the easiest way (in my opinion) would be to find the LCM (least common multiple)
To do so, first, you would need to list the factors of 6 and 9 in order
6: 6 12 18 24 30
9: 9 18 27 36 45
Then, you can find the LCM by finding the same number that comes first in each list (18)
2. To find how many packets, all you have to do is divide 18 by 6 and 18 by 9 because there are 6 flowers in one packet, and 9 flowers in the other.
Hope this helps!
Im pretty sure its just 1
An obtuse triangle. I think.
The answer is <span>B.
In a rhombus, all four angles are congruent.</span>
Tan⁴x - sec⁴x = 1 - 2sec²x
tan²x = sec²x - 1
tan⁴x - sec⁴x = 1 - 2sec²x
(tan²x)² - sec⁴x = 1 - 2sec²x
(sec²x - 1)² - sec⁴x = 1 - 2sec²x
(sec²x)² - 2 * sec²x + 1 - sec⁴x = 1 - 2sec²x
sec⁴x - 2 sec²x + 1 - sec⁴x = 1 - 2sec²x
sec⁴x can be cancelled:
- 2 sec²x + 1 = 1 - 2sec²x
1 - 2sec²x = 1 - 2sec²x
