Be nice if we were sure of the question. I will guess that you want the hypotenuse.
c^2 = a^2 + b^2
a = 6 km
b = 6 km
c^2 = 36 + 36
c^2 = 72
c = sqrt(72)
c = sqrt(9 * 8)
c = 3*sqrt(8)
c = 3 * 2.83
c = 8.49
Answer:
It's -7
Step-by-step explanation:
Use the GCF of the terms to write the expression as the product of two factors with integer coefficients.
-2x3 - 4x2 + 4x
