7.236 divided by .12 is 60.3
29, 31, 33, 35
29+31+33+35=128
The first one !!!! Hope this helps

The volume of a cone is found using the formula . Substitute the values V = 1309 and h = 8. Solve for r.
<u>Answer:</u>
The solution of x^2 + 6x + 6 is x = -1.2679 or -4.7320
<u>Solution:</u>
A two degree polynomial equation is given in the question.
We have been asked to solve it to find the value of ‘x’.
The given equation is:
<u><em>There are two ways to solve this equation.
</em></u>
We can either factorise it or use the quadratic equation formula. For factorising it, it has to satisfy certain conditions.
The condition is should be a perfect square otherwise the equation is not factorable.
a=1,b=6,c=6
On substituting the values of a,b and c, we get:
Which is not a perfect square.
Hence we have to use the quadratic equation is
By substituting the values of a,b and in the quadratic equations. We get;
<u><em>The two roots of x are:</em></u>
On solving both the equations we will get the roots of the given equation, which are:
x = -1.2679 or -4.7320
