Before getting started, you’ll want to make sure your patio is completely clear. Find a place away from your work area to stash patio furniture, dining sets, planters, grills, toys and anything else that may be damaged by free-flowing water or cleaning solutions. Your work area should ideally be as empty as you can get it.  Bring lightweight furniture inside, and move heavier pieces to the yard, sidewalk or a covered porch. Prolonged exposure to moisture can cause metal furniture and appliances to rust. Use a broom to dislodge as much loose debris from the patio as you can. This will make it easier to reach the more stubborn stains underneath, as well as give you an idea how extensive the cleaning methods you employ will need to be. Substances like compact dirt, dried mulch or sidewalk chalk may need to be scrubbed by hand using an abrasive sponge. Once you’ve swept the concrete, hose it down with a heavy stream of water. Push the dirt off to an adjoining section of the yard to drain. The concrete will then need time to dry before you can move on to other, more involved methods.  If it’s been awhile since you last cleaned your patio, add some mild liquid dish detergent to a bucket of warm water to make a soapy rinse. The surfactants in the soap will help break up dirt and oil more effectively.  In some cases, a good hosing may be all you need to remove a thin layer of dirt and sediment.

Q: The Pythagorean Theorem can easily be used to calculate the straight-line distance between two points in the X-Y plane. All you need to know are the x and y coordinates of any two points. Usually, these coordinates are written as ordered pairs in the form (x, y). To find the distance between these two points, we will treat each point as one of the non-right angle corners of a right triangle. By doing this, it's easy to find the length of the a and b sides, then calculate c, the hypotenuse, which is the distance between the two points. In a typical X-Y plane, for each point (x,y), x gives a coordinate on the horizontal axis and y gives a coordinate on the vertical axis. You can find the distance between the two points without plotting them on a graph, but doing so gives you a visual reference that you can use to ensure your answer makes sense. Using your two points as the corners of the triangle adjacent to the hypotenuse, find the lengths of the a and b sides of the triangle. You can do this visually on the graph, or by using the formulas |x1 - x2| for the horizontal side and |y1 - y2| for the vertical side, where (x1,y1) is your first point and (x2,y2) is your second.  Let's say our two points are (6,1) and (3,5). The side length of the horizontal side of our triangle is:  |x1 - x2| |3 - 6| | -3 | = 3    The length of the vertical side is:  |y1 - y2| |1 - 5| | -4 | = 4    So, we can say that in our right triangle, side a = 3 and side b = 4. The distance between your two points is the hypotenuse of the triangle whose two sides you've just defined. Use the Pythagorean Theorem as you normally would to find the hypotenuse, setting a as the length of your first side and b as the length of the second. In our example using points (3,5) and (6,1), our side lengths are 3 and 4, so we would find the hypotenuse as follows:  (3)²+(4)²= c² c= sqrt(9+16) c= sqrt(25) c= 5. The distance between (3,5) and (6,1) is 5.
A: Define two points in the X-Y plane. Plot your two points on a graph. Find the lengths of the non-hypotenuse sides of your triangle. Use the Pythagorean Theorem to solve for the hypotenuse.

Article: A good way to reach a potential convert is to present Bible passages that they can read and work through. The participants should learn which Bible passages are good for evangelizing and how they can show others the value of the Bible through the passages. Bring in a few example passages that you feel are useful for reference when evangelizing.  For example, you may use passages from the Gospel that invite the reader to seek salvation in Jesus Christ, such as Luke 10:25-28, Matthew 4:17, or Matthew 11:28-30. You can also use passages from the Letters from Paul that focus on invitations to faith, such as Romans 10:9-10, Romans 10:13, and Acts 16:30- 31. Have participants do a deep dive into the Bible to identify passages that they feel would be inviting to potential converts. Ask them to look at passages that explain the meaning of faith in a powerful way. Have participants discuss why they were drawn to a particular passage with the rest of the group so everyone can learn together. You may assign this as homework for participants so they can spend some time reading and choosing passages. Encourage participants to find deeper meaning by asking them to express what the passage means to them. Have them explain the passage using their own language and understanding. This can help them better explain the passage to potential converts when they evangelize. For example, you may ask participants, “What does the passage mean to you as a person of faith?” and “How would you explain the meaning of this passage to someone outside the faith?” Understanding the teachings of the Bible is crucial to learning how to evangelize effective. You may ask participants to take time in the session to pray on specific passages in the Bible so they can connect in a more meaningful way. This may be a good way to wrap up a training session or open a training session to get participants focused on Biblical study.
Question: What is a summary of what this article is about?
Discuss passages that address evangelism. Encourage participants to find passages that discuss evangelism. Have participants explain a passage in their own words. Ask participants to pray on specific passages to find deeper meaning.
