Answer:
$23
Step-by-step explanation:
1 phone case = $12
4 phone cases = 12 * 4 = $48
Table = $25
4 phone cases - Table = 48 - 25 = $23
Ok, I'm going to start off saying there is probably an easier way of doing this that's right in front of my face, but I can't see it so I'm going to use Heron's formula, which is A=√[s(s-a)(s-b)(s-c)] where A is the area, s is the semiperimeter (half of the perimeter), and a, b, and c are the side lengths.
Substitute the known values into the formula:
x√10=√{[(x+x+1+2x-1)/2][({x+x+1+2x-1}/2)-x][({x+x+1+2x-1}/2)-(x+1)][({x+x+1+2x-1}/2)-(2x-1)]}
Simplify:
<span>x√10=√{[4x/2][(4x/2)-x][(4x/2)-(x+1)][(4x/2)-(2x-1)]}</span>
<span>x√10=√[2x(2x-x)(2x-x-1)(2x-2x+1)]</span>
<span>x√10=√[2x(x)(x-1)(1)]</span>
<span>x√10=√[2x²(x-1)]</span>
<span>x√10=√(2x³-2x²)</span>
<span>10x²=2x³-2x²</span>
<span>2x³-12x²=0</span>
<span>2x²(x-6)=0</span>
<span>2x²=0 or x-6=0</span>
<span>x=0 or x=6</span>
<span>Therefore, x=6 (you can't have a length of 0).</span>

Question
If someone around 831,982 to 830,000 and then someone else rounds 831,982 for 800,000 who would be correct?
Answer:
Hi, There! Mika-Chan I'm here to help! :)
<em><u>First We Need to know If we're rounding to the Nearest Hundred thousand or Not.</u></em>
<u><em>So The Answer would Be 800,000 If your Going to Round to the nearest Hundred </em></u>
<u><em>But If We're rounding to The Nearest ten Thousand The Answer would be 830,000</em></u>
:D hope this Helps you!
Answer: I encourage you to ask real questions for the sake of others.
