Q: Make sure you draw it according to any required specifications. If your number line has no specifications, just make sure to include positions for both x{\displaystyle x} values your found previously. Include a few values above and below these to make the number line easier to interpret. For example, since the roots for the inequality x(x+4)<21{\displaystyle x(x+4)<21} are x>−7{\displaystyle x>-7} and x<3{\displaystyle x<3}, draw a number line that includes positions for -7 and 3. Plot the points by drawing a circle over their position on the number line. If the inequality is greater than (>{\displaystyle >}) or less than (<{\displaystyle <}), draw an open circle. If the inequality is greater than or equal to (≥{\displaystyle \geq }) or less than or equal to (≤{\displaystyle \leq }), fill in the circle on the number line, since the values are included in the set. For example, since the roots your are working with are x>−7{\displaystyle x>-7} and x<3{\displaystyle x<3}, you would draw open circles at the -7 and 3 positions on the number line. If x{\displaystyle x} is greater than the value, draw a line pointing to the right on the number line, since the included values will be larger than x{\displaystyle x}. If x{\displaystyle x} is less than the value, draw a line pointing to the left on the number line, since the included values will be less than x{\displaystyle x}. If the included values are between two numbers, you will draw a line between the two plotted points. For example, since you want to show that x>−7{\displaystyle x>-7} but also x<3{\displaystyle x<3}, you need to draw a line between -7 and 3 on the number line.
A: Draw a number line. Plot the x{\displaystyle x} values on the number line. Draw arrows or lines indicating the included values.

Q: You may not want or need to cover the treated wart with a bandage if it's not causing you discomfort. But, if you have a planter wart on your foot, you'll probably need a special cushioned bandage to make walking more comfortable. Most bandages for planter's warts are circular and cushioned around the edges. The center of the bandage isn't as cushioned, so it takes pressure off the wart. This is what makes walking more comfortable. You may notice a blister or blood blister form a few hours after freezing the wart. The area may burn a bit and the wart might look irritated. Healing usually takes four to seven weeks. Don't break the blister or scrape off any dead skin. This can expose the tissue underneath the the virus, making the wart grow back. If the wart doesn't look like it's getting smaller, you may need to re-apply the freezing compound. Wait 2 to 3 weeks and repeat the freezing process for OTC kits. If you received a liquid nitrogen treatment, make an appointment with your dermatologist to reassess and see if another application is necessary.  Warts can be sometimes hard to remove.  Sometimes the doctor might want to try a couple of methods at one time in for to facilitate removal. Understand that since OTC compounds don't get as cold as the liquid nitrogen used by doctors to freeze warts. Because of this, it may take several treatments and more time before your wart falls off.
A: Use bandages. Leave the wart alone. Re-treat if needed.

Q: Before getting down and scrubbing your grout, you need to do a basic once-over with your favorite cleaner. If you cleaning floor grout, sweep and mop. For bathroom and kitchen counter grout, spray, and wipe it down with your favorite cleaner. In a small bowl, mix hydrogen peroxide and baking soda to form a thick paste. The parts of each may vary depending on the consistency and thickness you prefer to work with. Use your finger or a toothbrush to spread the paste onto your grout. Start in a small area only, no larger than 1-2 square feet. Keep the solution thick and completely the coat the grout. Allow it to set for 5-10 minutes. Use a small brush such as a toothbrush (electric preferably) for scrubbing at the grout. Apply firm pressure over a small area to lift dirt and stains. If the grout is still dirty, add more of your paste and scrub again after letting it set for a few minutes. Continue adding the cleaning mixture to the grout and scrubbing it off. Work slowly to ensure that you have gotten all your grout cleaned up. Use a damp rag to wipe off the remaining paste on your tile. Finish by cleaning your tiles as usual with a spray cleaner for counters or a mop and soap for floors.
A:
Clean up your tiles. Create your paste. Spread your mixture. Begin scrubbing. Finish your space. Wipe up your tile.
