To calculate the area you would do L*w=a² and that is how much ft of rug you will need
Wait I got it put any number in number of tickets than multiply that number by 27 to get total cost
The Pythagorean Theorem states that "When a triangle has a right angle of (90°), the square of its hypothenuse is equal to the sum of the squares of the other two sides."
The hypothenuse is the longest side of the triangle.
For example: A triangle has 3 sides. Side A, Side B, and Side C (hypothenuse).
Side A = 3; Side B = 4; Side C = 5; To check if the theorem is true, we must square all sides.
Side A = 3² = 9; Side B = 4² = 16; Side C = 5² = 25
Pythagorean theorem: The square of the hypothenuse is equal to the sum of the squares of two sides.
<span>Side A² + Side B² = Side C² ==> 9 + 16 = 25 ==> 25 = 25</span>
Answer:
y = -3x + 8
Step-by-step explanation:
You have to find the slope first using the formula 
Insert any two points in the equation (1,5) and (2,2) and you get -3.
Then, you do any x value times the slope (1*-3 = -3) and add so that it equals the corresponding y value (8).
This makes it y = -3x + 8.
Answer: none
1) combine like terms: 4x + 8 = 4x - 13
2) Add 13 to both sides (addition property of equality)
3) Subtract 4x from both sides (subtraction property of equality)
4) 21 does not equal 0
