The angles in an equilateral triangle are 60 degrees.
sin 60 = 9 / h where h is hypotenuse ( = side of the triangle)
h = 9 / sin 60 = 10.392
Perimeter = 3 * h = 31.18 to nearest hundredth
Answer:
The quotient of a number and 9 means n divided 9.

Answer:
y = 3*(x^2) + 9x -30
Step-by-step explanation:
y=3(x+5)(x-2)
y = (3*x + 3*5) * (x - 2)
y = (3*x + 15) * (x - 2)
y = 3*x*x + 3*x*(-2) + 15*x + 15*(-2)
y = 3*(x^2) - 6x + 15x - 30
y = 3*(x^2) + 9x -30
