Answer: x= -27
Step-by-step explanation: subtract 9 from both sides to get x by itself
A polygon is regular when all angles are equal and all sides are equal (otherwise it is "irregular"). This is a regular pentagon (a 5-sided polygon)
F(x) = x² + 2x - 1
f(2) = 2² + 2 · 2 - 1 = 4 + 4 - 1 = 7
f(-2) = (-2)² + 2 · (-2) - 1 = 4 - 4 - 1 = -1
f(3) = 3² + 2 · 3 - 1 = 9 + 6 - 1 = 14
f(-3) = (-3)² + 2 · (-3) - 1 = 9 - 6 - 1 = 2
The range = {-1; 2; 7; 14}
It is 29.
Angle at the centre is double the angle at the circumference.
The head is just in a different place.
It is the “ the angle at the circumference is half the angle at the circumference “
Multiply 1/8 by 560
answer: 70
