Answer= x^2-4
I hope this helps.
C=2pr, r=c/(2p)
a=pr^2, using r found above we get:
a=p(c^2/(4p^2))
a=(c^2)/(4p), since c=106.76 and we approximate pi as 3.14
a=(106.76^2)/(4*3.14)
a=11612.2176/12.56 cm^2
a≈924.54 cm^2 (to nearest one-hundredth of a square cm)
12x²-8x-15 should be your answer
$305.25 divided by $9.25 equals 33, so he worked 33 hours... hope this helped.
They are both equal. 3% converted to a fraction is .3
