Answer:
The value of x is -2 and 2.
Step-by-step explanation:
When solve an expression, you have to make the expression equals to 0 by moving all the terms to one side :
x² - 3x - 1 = -3x + 3
x² - 3x - 1 + 3x - 3 = 0
x² - 4 = 0
Next, you have to factorize and solve it :
x² - 4 = 0
x² + 2x - 2x - 4 = 0
x(x + 2) - 2(x + 2) = 0
(x + 2)(x - 2) = 0
x + 2 = 0
x = -2
x - 2 = 0
x = 2

Answer:
option (a)
Step-by-step explanation:
Length of long dimension = 11400 km
It means it is the length of major axis.
So, the length of semi major axis = 11400 / 2 = 5700 km
Thus, the length of semi major axis is 5700 km.
