1. You take 0.002 and multiply this by 0.2, then get your answer of 0.0004.
it would look like that (0.2) . (0.002)=0.0004
2. An area of a rectangle: a . b
a= 0.4km
b=0.07 km
a . b= 0.4km . 0.07km= 0.028 km^2

Answer:
the answer is x=3
Step-by-step explanation:
-3x=1-7
-3x=-6
-x=-6+3
-x=-3
x=3
Answer:
first option
Step-by-step explanation:
3x² - 18x + 5 = 47 ( subtract 5 from both sides )
3x² - 18x = 42 ( divide through by 3 )
x² - 6x = 14
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 3)x + 9 = 14 + 9
(x - 3)² = 23 ( take square root of both sides )
x - 3 = ±
( add 3 to both sides )
x = 3 ±
