Not quite sure what you mean by brackets, but you can get the solution to this equation in a few steps:
<span>(-2x - 1)</span>² <span>= 0 ... square root both sides to eliminate the squared binomial
</span>√(-2x - 1)² = √0 ... simplify; the square is canceled out and the root of 0 brings you back to 0
-2x - 1 = 0 ... solve like a two-step equation
-2x = 1
x = -1/2 is your x-value.

<u>Answer:
</u></h2>
The bearing of B from A is 28 degrees, approximately
The bearing of A from B is 180+28=208 degrees, approximately.
Step-by-step explanation:
The bearing of B from A is 28 degrees, approximately
The bearing of A from B is 180+28=208 degrees, approximately.
The reason for approximation is from distortion of image.
See attached image to understand ohw the measurement has been obtained.
Answer:
A
Step-by-step explanation:
(5x4) - 6 / 2 = x
Answer:
B (r= 1/6s)
Step-by-step explanation:
If you just work out each option, you'll see that "s" multiplied by 1/6 gets r.

- 485 - 319 = 166 more people
4.
- 14.5x + 80 > 500
- 14.5x > 420
- x > 420/14.5
- x > 29
5.
- 1.25x + 3 ≤ 28
- 1.25x ≤ 25
- x ≤ 25/1.25
- x ≤ 20 miles
6. <em>This seems a typo... 460 is likely $60</em>
- 60x + 145 ≤ 625
- 60x ≤ 625 - 145
- 60x ≤ 480
- x ≤ 480/60
- x ≤ 8 days
