name the characteristics a shape has to have to be defined as the following Quadrilateral triangle and square
Answers
1. Quadrilateral- Quadrilaterals should have four sides and four corners. As long as these two are present, you can call any shape a quadrilateral regardless of how it is formed.
2. Square- A square is a quadrilateral, so it must contain four sides and four corners. However, a square has its sides and corners equally made.
3. Triangle- A triangle should have three sides or vertices and three corners.

1) we calculate the area of the rectangle:
area (rectangle)=lenght x width
area (rectangle)=36 ft x 20 ft=720 ft².
2) we calculate the area of the triangle:
area (triangle)=(base x height) / 2
area (triangle)=(6 ft x 5 ft) / 2=15 ft².
3) we calculate the area of this pool:
area (pool)=720 ft²-15 ft²=705 ft²
Answer: the area of the pool is 705 ft².

Step-by-step explanation:
6000-1800 = 4200 divided by 1/4 = 1050
6,000 - 1,800 = 4,200
4,200 / 1/4 (or 25)

a. Okay, so you multiply the 4.7 and 2.9 together, and then add the exponents
13.63 * 10^10
But we are not done. There can only be one digit in front of the decimal point. So, you move the 13.63 back one place so 1.363. But we have to do this to both sides, so the answer is 1.363 * 10^11.
b. Now you divide the 5.8 and 2, and subtract the exponents.
2.9 * 10^-5
The negative exponent is fine in this case if you were wondering.
c. Expand the scientific notation to 1500, then add the 2491 and then put that in scientific notation is what I would do. You can also express 2491 in scientific notation and add them. Either way you will get 3.991 * 10^3
d. Same thing here except with subtraction. The answer is 6.5 * 10^-4.
This was a little long, sorry. Let me know if you need further explanation. I hope this helps.
