Answer:
The second map is larger in size
Step-by-step explanation:
Map 1 = scale of 1 inch to 100
Map 2= scale of 1 inch to 500
Lets assume, the parks have a length of 3000 ft and a width of 2000ft.
Map 1
Length = 3000/1000 = 3ft
Width = 2000/1000 = 2 ft
Map 2
Length: 3000/500 = 6 ft
Wdght: 2000/500 = 4ft
In both length and width, second map is larger in size.
You can either use the Pythagorean theorem right away (a = -3, b = 27, c = 1200) or Try factoring the polynomial to find the zeros.
I would factor and start by dividing everything by -3.
<span>-3x^4 + 27x^2 + 1200 = 0
-3(x^4 - 9x^2 - 400) = 0
If you divide by -3 on both sides you see that the -3 is now gone. 0/-3 = 0
x^4 - 9x^2 - 400 = 0
factor further or use Pythagorean theorem.
(x² - 25)(x² + 16) = 0
Solve for the x-values by setting each one equal to zero.
x² - 25 = 0
x² = 25
x is +5 or -5
x² + 16 = 0
x² = -16
x = √(-16)
Two non-real solutions
x is +4i or -4i
