Answer:
12.5mg
Step-by-step explanation:
500ml÷100ml= 5
2.5mg×5= 12.5mg
You add because
2842-(-282)
=2842+282
thus the answer will be 3124
You just switch the signs:
So the polynomial would be, -5x^2+3x+9
I hope this helps!
(y^2-y-12)/(y^2-2y-15) factor both the numerator and denominator...
(y^2-4y+3y-12)/(y^2-5y+3y-15)
(y(y-4)+3(y-4))/(y(y-5)+3(y-5))
((y-4)(y+3))/((y-5)(y+3)) so the (y+3) terms cancel leaving
(y-4)/(y-5)
