To solve this problem you must apply the proccedure shown below:
1. You must use the formula for calculate the surface area and the volume of the tank:
2. Solve for 
in the second equation and substitute it into the first one.Then, you have:
3. Now, derivate:
4. When you solve for 
, you obtain:
![2x^{3}-256=0\\ x=\sqrt[3]{\frac{256}{2}} \\ x=5.03](https://tex.z-dn.net/?f=%202x%5E%7B3%7D-256%3D0%5C%5C%20x%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B256%7D%7B2%7D%7D%20%20%5C%5C%20x%3D5.03%20)
5. Now, you must calculate :
Therefore, the dimensions are:
The sides of the base of the tank: 
The height of the tank: 
(X+5)²=4/4
X+5=1, X+5=-1
X=1-5 X=-1-5
X=-4 X=-6

Step-by-step explanation:
Answer:
107%
Step-by-step explanation:
Emma spending 7% more on the sweater than the shoes can be represented by x + 7%, where x is the price of the shoes.
The shoes are worth 100%, or one whole, because you can't buy half a shoe or more than one whole shoe, etc.
So to find how much more the sweater is, add 100% to 7%, or how much more the sweater is.
100% + 7% = 107%
The cost of the sweater is 107% of the cost of the shoes.
<span>13 more than 4 times a number is negative 91
</span>Convert to numbers:
13 more than 4: 4+13
times a number: (x)
is negative 91: = -91
Put it together:
4x+13=-91
x = -26
