= i
x² = - 12 ( take square root of both sides )
x = ±
= ±
= ± 2i
Answer:
9
Step-by-step explanation:
Area of a Circle = PI * radius^2
= 3.14 * 1.8^2
= 3.14 * 3.24
= 10.17 meters^2

Answer:
See below.
Step-by-step explanation:
The triangles are similar because the angles marked 125 are equal and the sides either side of these angle are in the same ratio:
1.3 / 2.5 = 2.6 /5.
If we are given the length of AE we would find CF from the equation:
1.3 / 2.5 = CF / AE
CF = (1.3 * AE) / 2.5.
