Answer:
64*x^-6
Step-by-step explanation:
Simplify Using Laws of Exponent (4x^-2)^3
Given data
(4x^-2)^3
Let us open the bracket
=4^3*x^-2*3
=64*x^-6
=64x^-6
Hence the equivalent is
speed =48mph
distance = 180 miles
we know that
time = distance / speed
..........Answer
x=13
because they're alternate adjacent angles:
5x=78-x
6x=78
