Sonja [21]

I found the image that should have accompanied this problem.

Given:
equilateral triangle with sides that measures 7cm.
hexagonal shape meaning 6 sides or 6 equilateral triangles used.

Area of an equilateral triangle = √3/4 * a²
A = √3 /4 * (7cm)²
A = 1.73/4 * 49cm²
A = 21.20 cm²

21.20 cm² * 6 tiles = 127.20 cm² ARea of the hexagon.

What is the standard form for 25x²+4y²+50x-24y-39=0

Thepotemich [5.8K]

25x² + 4y² + 50x - 24y - 39 = 0
25x² + 50x + 4y² - 24y - 39 = 0
25x² + 50x - 39 = 0 4y² - 24y - 39 = 0
x = -b + √b² - 4ac y = -b + √b² - 4ac
 2a 2a
x = -50 + √(-50)² - 4(25)(-39) y = -(-24) + √-(-24)² - 4(4)(-39)
 2(25) 2(4)
x = -50 + √2500 + 3900 y = 24 + √-576 + 624
 50 8
x = -50 + √6400 y = 24 + √48
 50 8
x = -50 + 80 y = 24 + √16 × 3
 50 8
x = -50 + 80 y = 24 + √16 √3
 50 8 
x = -50 + 80 y = 24 + 4 √3
 50 8
x = -50 + 80 y = 24 + 4 √3 
 50 8
x = -50 + 80 x = -50 - 80 y = 24 + 4 √3 y = 24 - 4 √3
 50 50 8 8
x = 30 x = -130 y = 28 √3 y = 20 √3
 50 50 8 8
x = 3 x = -13 y = 28 √3 y = 20 √3
 5 5 8 8
(x, y) = (3, 26 √3) (x, y) = (-13, 20 √3 )
