Answer:
option b
Step-by-step explanation:
you can't take out anything, not an x or a 2
The correct answer is choice C. Here is the reason. If you substitute the information into the formula this is what it would be:
A = bh/2
13 = x (6x + 1)/2
13 = (6x^2 + x)/2
26 = 6x^2 + x
0 = 6x^2 + x - 26
The solution to the given quadratic equation is;
x = -2 and x = 1/5
<h3>Roots of quadratic Equation </h3>
We are given the quadratic function;
(x + 2)(5x - 1) = 0
In quadratic functions, when it is expressed as;
(x + a)(x - b) = 0, what this means is that the factors of the quadratic equation or polynomial are; (x + a) and (x - b)
What that means is that the roots will be gotten from;
(x + a) = 0 and (x - b) = 0
Thus, applying the concept above on roots of a polynomial to our question, we have;
(x + 2) = 0 and 5x - 1 = 0
Solving them gives us;
x = -2 and x = 1/5

The correct answer is A = 2 x pi x r x h. So basically the answer is C. Hope I helped! :)
Calculate rank percentile in Excel
To calculate the rank percentile of a list data, you can use a formula. Select a blank cell that you will place the rank percentile at, type this formula =RANK. EQ(B2,$B$2:$B$9,1)/COUNT($B$2:$B$9), press Enter key and drag fill handle down to calculate all rank percentiles.
