I'll just take the points thanks XD
You would set up the problem like this: 3n-25=38
To solve for n:
3n-25=38
+25 +25 (Add 25 to both sides)
3n=63
/3 /3 (Divide by 3 on both sides)
n=21
The answer is 21.
7x^2 - 16x - 8 = 0
using the quadratic formula x = [ -(-16)+/- sqrt((-16^2 - 4*7-8] / 2*7
= (16 +/1 sqrt 480) / 14
= 2.71, -0.42 to nearest hundredth
