Answer:
The answer is below
Step-by-step explanation:
We need to prove that:
(Root of Sec A - 1 / Root of Sec A + 1) + (Root of Sec A + 1 / Root of Sec A - 1) = 2 cosec A.
Firstly, 1 / cos A = sec A, 1 / sin A = cosec A and tanA = sinA / cosA.
Also, 1 + tan²A = sec²A; sec²A - 1 = tan²A
The answer would be standard deviation.
So you would distribute what's in the parenthesis and end up with 4x-2x-6=x+1, then you combine like terms and end up with 2x-6=x+1, now you can add 6 to both sides or subtract 1 both sides (basically anything goes for this step just make sure you apply the same thing on both sides) so I'll add 6 and continue just to show you... then you end up with 2x=x+7 then you subtract 1x on both sides to get x=7. sorry it's a lot hopefully you get it know!

Answer:
- 1656 acres left
- 644 acres sold
- $32,200,000
Step-by-step explanation:
1. The number of acres sold is ...
28% × 2300 = 0.28 × 2300 = 644
Then the number of acres Emmet has left will be ...
2300 -644 = 1656 . . . acres left
__
2. Emmet sold 644 acres.
__
3. At $50,000 per acre, the value of the land sold was ...
$50,000 × 644 = $32,200,000 . . . . paid by the developer
The answer is 122/495. Hope this helps!
