What is the value of f(x) when x = -3?
f(x)=2x^2=4x+10
a) -14
b) -8
c) 16
d) 34

C) 16

Step-by-step explanation:

f(x)=2x^2+4x+10

Let x = -3

f(-3) = 2(-3)^2 +4(-3) +10

       = 2(9)- 12+10

       = 18 -2

       = 16

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
