Answer:
D) x=
Step-by-step explanation:
The quadratic formula is : 
A in terms of this question=9
B in terms of the question is 12
C in terms of the question is -24.
This question is an example of a quadratic equation. To work this out you may first need a calculator. The first step is to substitute the values of a,b and c into the formula. So once substituted the formula of becomes 
. Although when written in a calculator there will not be a plus and minus button and so you would have to do this separately.
However when substituting the values it would be best practice to put them in brackets.
1) Substitute the values into the equation for +.
2) Substitute the values into the equation for -.
Answer:
C.
Step-by-step explanation:
I cant really explain it but i had the same question and had the answer worked out on the paper
Hope it helps :3 (tell me if it was right or wrong so i know if i need to fix something later)
In light of the fact that point y is the point at which segment xz is divided, the value of the variable an is equal to 4.
<h3>How can I determine what the value of the variable an is?</h3>
Due to the fact that point y divides segment xz into two distinct halves, the following equation may be used to get segment xz's total length:
xz = xy + yz.
The following are the parameters for the test:
xy = 7a. yz = 5a. xz = 6a + 24.
As a result, we need to substitute into the equation and then solve for a.
xz = xy + yz
6a + 24 = 7a + 5a
12a = 6a + 24
6a = 24
a = 24/6
a = 4.

Answer:
26 ft square by 13 ft high
Step-by-step explanation:
The tank will have minimum surface area when opposite sides have the same total area as the square bottom. That is, their height is half their width. This makes the tank half a cube. Said cube would have a volume of ...
2·(8788 ft^3) = (26 ft)^3
The square bottom of the tank is 26 ft square, and its height is 13 ft.
_____
<em>Solution using derivatives</em>
If x is the side length of the square bottom, the height is 8788/x^2 and the area is ...
x^2 + 4x(8788/x^2) = x^2 +35152/x
The derivative of this is zero when area is minimized:
2x -35152/x^2 = 0
x^3 = 17576 = 26^3 . . . . . multiply by x^2/2, add 17576
x = 26

As the attached graph shows, a graphing calculator can also provide the solution.
Answer:
The situation is Multiplicative.
The equation will be 
Step-by-step explanation:
We are given the table:
Input (x) 5 8 11
Output (y) 10 16 22
Looking at the table, we see that the value of x is doubled to get value of y
Looking at the trend: 5(2) = 10
8(2) = 16
11(2) = 22
The value of x is multiplies by 2 to get value of y.
So, The situation is Multiplicative.
Now, The equation will be
because we saw the trend, that every value of x is multiplied by 2 to get value of y.
