Answer:
length = 10
width = 5
Step-by-step explanation:
So first you divide 8 from 400 which equals 50.
Then so the length and the width has to equal 50 when they are times-ed, and the length is double the width.
So the length is 10
and the width is 5
Given that the volume of a rectangular prism is length x width x height, this problem can be solved by setting up the equation 2w * w * 8 = 400, where w is the width and 2w is the length. Solving this equation, we find that the width is 5 feet and the length is 10 feet.
In mathematics, the volume of a rectangular prism is given by the formula length x width x height. We are given that the volume of the storage container is 400 cubic feet, its height is 8 feet, and the length is twice the width. Let us denote the width as w, then the length is 2w.
From the given volume formula, we have:
Length x Width x Height = Volume
Substituting the values, we get:
2w * w * 8 = 400
Solving this equation, we find:
w^2 = 25
Taking the square root of both sides, we get:
w = 5
Substituting w=5 into 2w, we find the length:
Length = 2*5 = 10
So the width of the container is 5 feet and the length is 10 feet.

Answer:
B & D
Step-by-step explanation:
The quadratic formula can be used to solve for x for any quadratic. Recall a quadratic is any function whose highest exponent known as degree is 2. Looking at the answer selections, A has one term with exponent 3. This isn't possible in the formula. Looking at answer C, the term with exponent 2 has the same coefficient on each side of the equal sign. When it is rearranged these will cancel out no exponent of 2 will be in the equation anymore. Only B & D work after being rearranged and simplified
The two equations after simplifying will give quadratic equations are:-
x ²-6x-7=2x² and 5x²-3x+10=2x².
The polynomial having a degree of two or the maximum power of the variable in a polynomial will be 2 is defined as the quadratic equation and it will cut two intercepts on the graph at the x-axis.
Solving for the quadratic equation:-
Option B:-
x ² - 6x - 7 = 2x²
- 2x² + x ² - 6x - 7 = 0
x ² + 6x + 7 = 0
Option D:-
5x² - 3x + 10 = 2x².
5x² - 2x². - 3x + 10 = 0
3x² - 3x + 10 = 0
Therefore two equations after simplifying will give quadratic equations are- x ²-6x-7=2x² and 5x²-3x+10=2x².
