Anna dad is 36. He is 9 times as old as she is .how old is Anna?

let anna age be x

so x (9)= 36

so anna age = 36/9 = 4

Anna is 4 years old.

Step-by-step explanation:

36 ÷ 9 = 4

Dad is 36 and to know Anna's age we need to divide by 9.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3
