Option C is correct

Multiply both sides of the equation by $\frac{1}{2}$

Step-by-step explanation:

Given the equation:

2x^2+12x = 32

Multiply both sides by $\frac{1}{2}$ we get;

$\frac{1}{2} \cdot (2x^2+12x) = \frac{1}{2} \cdot 32$

Simplify:

x^2+6x = 16

Subtract 16 from both sides we have;

x^2+6x-16=0

Therefore, the first step to solve the equation by completing the square is,

Multiply both sides of the equation by $\frac{1}{2}$

Number of Small Cones Sold=22

Number of Large Cones Sold=34

Step-by-step explanation:

Suppose,

Number of Small Cones Sold: s

Number of Large Cones Sold: l

For the condition that, larges cones sold were 12 more than small ones, equation would be

s-l=12....................................... (i)

and for the total revenue condition of $163

2*s+3.5*l=163.........................(ii)

By solving equation (i) and (ii) simultaneously, we get

s=22

and

l=34

Hence, small cones sold would be 22 and large cones sold would be 34.
