14*sin(60°) = 7√3 ≈ 12.124 . . . is the altitude
1. one line of symmetry
2. four lines of symmetry, also has rotational symmetry every 45°
3. no line of symmetry
4. two lines of symmetry
Answer:
See below
Step-by-step explanation:
LCM OF 9, 15 = 45
LCM OF 2, 3, 5 = 30
LCM OF 12, 28 = 84
3y + 11 + 7x - 30 + 5x + 14
3y + 12x - 5
3y = -12x + 5
y = (-12x + 5)/3
x = (3y - 5)/-12
