-1/2x+3=-x+7
Multiply throughout by 2x
-1+6x=-2x^2+14x
2x^2-8x-1=0
To find the sum of the interior angles of a hexagon, divide it up into triangles. The sum of each triangle is 180 degrees.
We get.... 4 x 180°=720°
So to sum it up....the sum of the interior angles of a hexagon is 720 degrees.
Answer:
≈ 11.66 units
Step-by-step explanation:
<u>Given points:</u>
<u>To find:</u>
- The distance between the given points
<u>The distance between two points is calculated by formula:</u>
- d= √((x2-x1)² + (y2-y1)²)
- d= √(((7-(-3))² + (-1-5)²) = √(10²+(-6)²)= √136 ≈ 11.66 units
<u>Answer is</u> ≈ 11.66 units
Second answer: f - 52 = 63.
20% * 300 = 2 * (10% * 300) = 2*30 = 60
