Solve the inequality -7x > 21. What is the graph of the solution?
1 answer:
<h2>Inequality</h2><h3>-7x > 21</h3>
<em>Divide both sides by −7. Since −7 is <0, the inequality direction is changed.</em>
<h3>x< 21/-7</h3><em>Divide 21 by −7 to get −3. </em>
<h3>x < −3</h3><em>The image is blurred, so options "A" and "B" are very similar, it may be a mistake. But you can check which one is correct.</em>

Explanation:
The formula for the surface area of a cylinder is
We then replace r with 10 and h with 25. Keep in mind that the diameter is 20 mm, so the radius is half that at 10 mm.
So that's how we get to
