Answer:

x = -2/7

Step-by-step explanation:

The excluded values of the given expression are all the values of x that will make the denominator (7x + 2) = 0. This is because you cannot divide by 0...at least in algebra.

1. 7x + 2 = 0

7x = -2

x = -2/7

Therefore, x = -2/7 is the excluded value.

Answer:

3rd option

Step-by-step explanation:

\frac{14x}{7x+2}

the denominator cannot be zero as this would make the expression undefined. Equating the denominator to zero and solving gives the value that x cannot be.

7x + 2 = 0 ( subtract 2 from both sides )

7x = - 2 ( divide both sides by 7 )

x = - \frac{2}{7} ← excluded value

PLEASE HELP W/ EXPEDITE AND URGENCY!
mariarad [96]
You don't need expedite and you don't need urgency.
All you need is the formula for the volume of a sphere.

     ==>        Volume of a sphere = (4/3) (pi) (radius)³ .

The question gave you the radius, and told you what to use
for 'pi', so now you have all the information you need.
