Answer:
1. 3-4-5 method
2. Rope method
3. Optical square method
Step-by-step explanation:
1. You'll need a measuring tape, two range poles, pegs, and three people.
The first person holds the zero mark between their thumbs and fingers, the second person holds the 3m mark on the tape between their thumbs and fingers, and the third person holds the 8m. When all sides of the rope are stretched, a triangle is created, and an angle near one is a right angle.
2. Wrap one loop of the rope around peg A with a peg through the other loop, draw a circle on the ground, place pegs B and C where the circle crosses the base line, and place peg D half way between pegs B and C, allowing pegs D and A to form lines perpendicular to the base line, forming a right angle.
3. Single and double prismatic squares are basic devices used to measure correct angles.
Answer:
1/2x*3

I looked it up....
Your answer would be 8n³ + 6n² - 4n - 20.
The horizontal method for simplifying binomials is to simply multiply the terms in the first bracket by the terms in the second bracket. Written out, this looks like:
(2n² × 4n) + (4n × 4n) + (4 × 4n) + (2n² × -5) + (4n × -5) + (4 × -5).
Then, we just need to do the operations in the brackets, which gives us:
8n³ + 16n² + 16n - 10n² - 20n - 20
And finally we collect the like terms to simplify, which means doing 16n² - 10n² = 6n², and 16n - 20n = -4n, so the final answer is 8n³ + 6n² - 4n - 20.
I hope this helps!
