So firstly, <u>the factor (4n - 5) cannot be further factored, so we will be focusing on 2n² + 5n + 3.</u>
So for this, we will be factoring by grouping. Firstly, what two terms have a product of 6n² and a sum of 5n? That would be 2n and 3n. Replace 5n with 2n + 3n:
Next, factor 2n² + 2n and 3n + 3 separately. Make sure that they have the same quantity on the inside of the parentheses:
Now we can rewrite this expression as<u> 
, which is your final answer.</u>
Hello from MrBillDoesMath!
Answer:
x >= 7
Discussion:
x + 5 >= 12 => add -5 to both sides
x + 5 -5 >= 12 - 5 => as 5-5 = 0 and 12 =5 = 7
x >= 7
Thank you,
MrB
The tangent half angle formula, one of several, is
We have θ is opposite 4 in the 3/4/5 right triangle so
Answer: 1/2
This is actually pretty deep. It says half the big acute angle in the 3/4/5 triangle is the small diagonal angle of the 1x2 rectangle. Similarly, the small acute angle in 3/4/5 triangle is twice the small diagonal angle of the 1x3 rectangle.
Answer:
4 and -6≤x<0
Step-by-step explanation:
6. 4
7. -6≤x<0
It's a number that can evenly be divided by numbers other than 1 or itself.
Example: 8. You can multiply the factors 2 and 4 and get 8 other than multiplying 8 and 1.
