Browse means to glance at, for example when looking at a magazine you most likely skim or glance at the small paragraphs next to the big pictures.
20%=0.20
20% of 18 is 18(0.2)=$3.6
$18-$3.6= $14.4

Step-by-step explanation:
Scale= 1:1,000,000
Scaled distance = 1.8 dm
Actual distance = 1.8*1,000,000 = 1,800,000 dm
Answer:
Step-by-step explanation:
A 2nd order polynomial such as this one will have 2 roots; a 3rd order polynomial 3 roots, and so on.
The quadratic formula is one of the faster ways (in this situation, at least) in which to find the roots. From 2x^2 + 4x + 7 we get a = 2, b = 4 and c = 7.
Then the discriminant is b^2 - 4ac, or, here, 4^2 - 4(2)(7), or -40. Because the discriminant is negative, we know that the roots will be complex and unequal.
Using the quadratic formula:
-4 ±√[-40] -4 ± 2i√10
x = ------------------ = ------------------
4 4
-2 ± i√10
Thus, the roots are x = ------------------
