It is already in the simplest form. It can be written as 0.216 in decimal form (rounded to 6 decimal places).
Step-by-step explanation:
x² + x - 2 = 0
x² + 2x - x - 2 = 0
x(x + 2) - 1(x + 2) = 0
(x + 2)(x - 1) = 0
x + 2 = 0 and x - 1 = 0
x = -2 and x = 1
So, f(x) has no solution if x = -2 or 1
Domain = {x | x ≠ 2 and x ≠ 1}
Answer:0.0
Step-by-step explanation:
Answer:
282.6
Step-by-step explanation:
Surface area of a cylinder
= 2pi rh + 2pi r^2
Given radius = 3
Height h = 12
Pi = 3.14
Surface area = 2 x 3.14 x 3 x 12 + 2 x 3.14 x (3)^2
2 x 3.14 x 3 x12
+
2 x 3.14 x 3 x 3
Simplify each sides
226.08 + 56.52
282.6
