Last option.

Step-by-step explanation:

 Given the equation:

Follow these steps to solve it:

- Subtract the fractions on the left side of the equation:

- Using the Difference of squares formula () we can simplify the denominator of the right side of the equation:

- Multiply both sides of the equation by and simplify:

- Multiply both sides by :

- Apply Distributive property and simplify:

- Divide both sides of the equation by -6:

- Factor the equation and solve for "m":

In order to verify it, you must substitute into the equation and solve it:

NO SOLUTION

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
