1, when you factor you get 6x(x^2-1)+4(x^2-1)=
Step-by-step explanation:
hope it helps you!!!!!!!!
I think we're not supposed to do more than 3 problems in one answer; certainly not five pages. Does the 1/3 mean there are 10 more to come?
I'll do the first page.
6)
Right triangle, opposite side of 10, adjacent side of 21,
tan x = opp/adj = 10/21
x = arctan 10/21 = 25.46°
Answer: 25
7)
cos x = adj / hyp = 10/14
x = arccos 10/14 = 44.42°
Answer: 44
8)
tan x = opp/adj = 12/24 = 1/2
x = arctan 1/2 = 26.57°
Answer: 27
9)
tan x = 31/32
x = arctan 31/32 = 44.09°
Answer: 44
10)
x = arctan 10/27 = 20.32°
Answer: 20
Answer:
The largest integer value that makes the inequality true is 9.

- Multiplication Property of Equality
- Division Property of Equality
- Addition Property of Equality
- Subtraction Property of Equality
Terms/Coefficients
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify.</em>
1x - 8 < 2x + 1
<u>Step 2: Solve for </u><u><em>x</em></u>
- Simplify: x - 8 < 2x + 1
- [Subtraction Property of Equality] Subtract <em>x</em> on both sides: -8 < x + 1
- [Subtraction Property of Equality] Subtract 1 on both sides: -8 < x
- Rewrite: x > -8
∴ we see that any number <em>x greater than -8</em> would work as a solution to the inequality. That would mean the next largest integer, 9, would be our answer.

Answer:
The room can be rented for 6 hours with $91.4
Step-by-step explanation:
If my guess was correct, there was a reservation fee of $47, and there was another fee of $7.4 per hour and the question is asking for how many hours can be rented with $91.4 and the variable t to represent the time.
First, $91.4-$47 as that is the reservation fee. $91.4-$47 = $44.4
Next, we figure out how many hours can we rent with $44.4. Since one hour of rental costs $7.4, t = 44.4/7.4
Finally, we just divide. This is a relatively simple question when thinking about how straightforward this is.
44.4/7.4 = 6
Recheck:
7.4*6 = 44.4
t = 6
