While riding her bike, Susan burns 450 calories every ½ hour. Based on this rate, how many calories will Susan burn if she rides the bike for 1¾? *

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
