Answer:
17.205 miles
Step-by-step explanation:
Since these directions form a 90-degree angle, we can use the Pythagorean Theorem.
14^2 + 10^2 = c^2
196 + 100 = c^2
296 = c^2
It doesn't have a perfect square root, you can either say that it is
or approximately 17.205 miles.
The quadratic formula is:
x=(-b±√(b^2-4ac))/(2a) for the quadratic of the form ax^2+bx+c
The discriminant is the (b^2-4ac) part of the quadratic formula.
Let d=(b^2-4ac). If:
d<0: There are no real roots.
d=0: There is one real root.
d>0: There are two real roots.
In this case the discriminant is:
(-6)^2-4*3*4
36-48
-12
Since -12<0 there are no real roots for the equation 3x^2-6x+4.

L=Length
W=Width

P=2L+2W=2(L+W) <em><--- Distributive property in action.</em>
1/10x200
= 1/10x200/1
= 200/10
=20
the answer is 20
if u dont understand, 1/10 means a part of 200 that is divided by 10 which means the number x10 =200. So if u dont understand, you can check answer this way: n*10=200
200/10=n
n= 20
