INPUT ARTICLE: Article: If cleaning with dish soap, vinegar, and rubbing alcohol does not work to remove hair dye from your carpet, make an ammonia-based cleaning solution. In a bowl or bucket, mix 2 cups (0.47 L)  of warm water with 1 teaspoon (4.9 ml) of dish soap and 1 tablespoon (15 ml) of ammonia. Open doors or windows to create ventilation while you use this solution, which can cause poisoning. Put on cleaning gloves to protect your hands. Dip a clean cloth in the ammonia solution and wring it out. Dab it onto the hair dye spill until the entire surface of the stain is covered. After covering the stain with the ammonia cleaning solution, leave it untouched to allow the solution to work. Set a timer or cell phone alarm to keep track of the time. Keep children and pets away from the area. After 30 minutes, dip a new, clean cloth in the ammonia solution. Wring it out. Dab on more solution and let it sit for 5 minutes this time. Once the stain is removed, wet a clean cloth or sponge with water. Dab the water onto the carpet thoroughly and use another clean cloth to blot it out. Let the carpet dry for 24 hours.

SUMMARY: Mix an ammonia cleaning solution. Apply the solution to the carpet stain. Let the solution sit on the stain for 30 minutes. Sponge on more solution every 5 minutes until the stain disappears. Sponge on cold water and air-dry.

In one sentence, describe what the following article is about: Depending on your ability level, you can work for a number of companies who hire English speakers to teach. You might be a conversation coach, a classroom teacher or teacher's assistant, or a summer language tutor.  If you have your certification in Teaching English as a Foreign Language (TEFL), you may be eligible for more jobs. You can get this certificate in the United States before you travel, or in many foreign schools. Instructors for college-prep courses or SAT training are also ways to get paid while traveling abroad. If you play a musical instrument, put up a flyer in a popular gathering spot announcing that you're teaching, together with your phone number. If you're a dancer, see if any local people want to learn your style of dance. You might teach yoga classes, art classes, improv classes. Anything that can be learned, can also be taught.  This type of instruction can be done formally, through a professional school or training academy, but is most often done informally, in public spaces or in private homes. Collect references and referrals as you travel. If people like your teaching style, ask them to put it in writing. Post these recommendations on your blog or website. Always carry a business card with your name and contact information. English isn't the only language in high demand. French, Spanish, Mandarin, Japanese, Korean, Arabic, Swahili and other languages are also in high demand, depending on your region. If you know another language, see if you can find students who want to learn it.  Good teachers in American Sign Language or other sign languages are also good to teach. Advertise at cafes and universities where students may wish for additional tutoring. If you're a certified scuba instructor, you can find work with outdoor adventure travel companies. Surfing instruction is another way to put your hobbies to good use, and make money while you travel.  Keeping a blog of yourself on the water will enhance your job applications, and make you teaching expertise more desirable. You don't need to be an expert to get hired for a job training beginners.
Summary: Teach English. Teach something you're skilled at. Teach other languages. Use your surfing or scuba skills to teach.

Sketch a trapezoid with the following measurements: left side of height b, right side of height a, and base of length a+b. Simply connect the tops of the left and right sides to complete the trapezoid. Divide the base of the triangle into lengths a and b so that two right triangles of lengths a, b, and c is formed. The third triangle will have two sides of length c and a hypotenuse of length d. The two smaller triangles are congruent (identical). The area of a trapezoid is: A = ½(b1 + b2)h where b1 is one straight side of the trapezoid, b2 is the other straight side of the trapezoid, and h is the height of the trapezoid. For this trapezoid: b1 is a, b2 is b, and h is a+b.  The area of this trapezoid is A = ½(a +b)(a+b) .  Expanding the binomial yields: A = ½(a2 + 2ab + b2). The area of a right triangle is: A = ½bh where b is the base of the triangle and h is the height. This trapezoid has been broken into three different triangles; therefore, the areas need to be added together. First, find the area of each one and then add all three together.  Because two of the triangles are identical, you can simply multiply the area of the first triangle by two: 2A1 = 2(½bh) = 2(½ab) = ab. The area of the third triangle is A2 = ½bh = ½c*c = ½c2. The total area of the trapezoid is A1 + A2 = ab + ½c2. Because both of these calculations are equal to the total area of the trapezoid, you can set them equal to each other. Once they’re set equal to each other, you can reduce the equation to its simplest form.   ½(a2 + 2ab + b2) = ab + ½c2. Multiply both sides by 2 to get rid of the ½: (a2 + 2ab + b2) = 2ab + c2. Subtract out the 2ab: a2 + b2 = c2. You’re left with the proof: a2 + b2 = c2.

One-sentence summary -- Draw a trapezoid with base a+b and sides a and b. Divide the trapezoid into three right triangles, two of which are congruent. Calculate the area of the trapezoid using the area formula. Find the area by summing the areas of the three triangles. Set the different area calculations equal to each other.
