-14n + q=rt-4n, for n
pentagon [3]
N = -1/10rt + 1/10q
= −14n+q+4n=rt−4n+4n
= −10n+q=rt
= −10n+q+−q=rt+−q
= −10n=rt−q
= -10n/-10 = rt-q/-10
So the answer is:
= n = -1/10rt + 1/10q

Using the quadratic formula to solve 4x^2-3x+9=2x+1, what are the values of x?
labwork [276]

Rewrite 4x^2-3x+9=2x+1 as 4x^2-5x+8 = 0


Here, a = 4, b = -5 and c = 8. Then,


5 plus or minus sqrt (25 -4(4)(8) )

x = ------------------------------------------------------

8

5 plus or minus sqrt (-103)

= --------------------------------------

8

5 plus or minus i*sqrt(103)

Then x = ----------------------------------------

8


= ---------------------------------------------

8
