Answer:
8) -8, -9
9) 4, 
Step-by-step explanation:
8) x² + 12x + 27
Solutions of a polynomial means the values of 
such that the polynomial becomes zero. 
.
We use the following formula to determine the solutions of a quadratic equation of the form: 
In this equation, 
Substituting in the formula, we have:
Taking 2 common outside we get:
Therefore, we get two solutions viz, x = -3, -9.
9) 2x² - 9x + 4 = y
X- intercepts of a polynomial means the value of x such that y = 0. It means the roots of the polynomial.
Solving the equation using the formula above, we get:
The values of x = 4, .
Hence, the answer.
Answer:
see below
Step-by-step explanation:
A: radius of 12 ft
Changing to meter
12 ft * .305 m/ ft =3.66 meter
The radius is 3.66 meters
The diameter is twice the radius = 2*3.66 =7.32 meters
The circumference is
C = pi*d = 3.14 * 7.32 =22.9848 = 22.98 meters
B diameter is 7.5 meters
Pool B has a bigger diameter
C = pi * d = 3.14 * 7.5m = 23.55 meters
The difference is .57 meters
