Find AC please, help is very much appreciated.
fenix001 [56]

Answer:

AC ≈ 67.9

Step-by-step explanation:

15² = 9 (3x + 1 + 9)

225 = 9 (3x + 10)

225 = 27x + 90

135 = 27x

x ≈ 19.29

AC = (3x + 1 + 9)

AC = 3 (19.2857...) + 1 + 9

AC = 57.857... + 1 + 9

AC =  57.857... + 10

AC ≈ 67.9

Luther evaluated 23 as 9 and Wade evaluated 32 as 9. Are both students correct? Explain why or why not.
CaHeK987 [17]
The answer 

let  A= 2^3 and B=3^2

the main formula is as following:

a^n = axaxax ....xa (n times), for all n upper than or equal 1
 for example 
a^3 = a x ax a

in our case 
 A= 2^3 = 2x2x2= 4x2 =8
B=3^2 = 3x 3= 9
so, Luther's evaluation was wrong, by contrast <span>Wade evaluated 32 as 9 correctly
