I'm guessing it would be -4 below sea level because if your at sea level, and go down, then it would be -4 below sea level.
Answer:

Step-by-step explanation:
Assumption:
<em>Something is missing in question. If we see deeply it is apparent that there is some issue with option b i.e. </em><em>B) 8 − 4x 10 = 4 + 2x </em><em>we assume that the questioner want to type </em><em>B) 8-4x^10 = 4 + 2x.</em>
Answer:
The correct answer is <em> </em><em>B) 8-4x^10 = 4 + 2x.</em>
Step-by-step explanation:
All equations given is the question can be solve easily to determine the value of x. However if we solve equation mentioned in option b we cannot get single answer easily.
For example value of x in eq given in option A
15x + 123 = 5x+4
1oX = -119
X = -119/10
The answer is B, but C is a pretty good answer too.LOL.
Answer:
Step-by-step explanation:
<em>(5√3*√3)+(5√3*5)+(-1*√3)+(-1*5) </em>
<em>5*3+25√3-√3-5 </em>
<em>15+24√3-5 </em>
<em>**24√3+10** </em>
<em></em>
<em>Then to solve the second, apply division rules within the radical. This means you can cancel an m^1 and n^4 from the bottom and top of the fraction. This leaves... </em>
<em>3√(88m^19*n^8) </em>
<em>(That might be all you need to do, otherwise you can take the square root of each number in the term giving... </em>
<em>3(√88)*m^9.5*n^4)</em>
