Answer:
its 11/4.5
Step-by-step explanation:
Answer:A
Step-by-step explanation:
18-(3xeach #)=
All are less than 10
We do as follows:
let x = amount of 45% solution
y = amount of 30% solution
overall balance => x + y = 450
acid balance => .45x + .30y = .40(450)
Solving simultaneously, we will have:
x = 300 mL
y = 150 mL
This is assuming that partial molar properties does not affect the volume greatly. Hope this answers the question. Have a nice day.
Answer:
Step-by-step explanation:
f(x)=x²+2
a.
f(a)=a²+2+2=a²+4
b.
f(a+2)=(a+2)²+2=a²+4a+4+2=a²+4a+6
c.
f(c+d)=(c+d)²+2=c²+d²+2cd+2
