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
Answer:
256x * 16
Step-by-step explanation:
(4x * 4x * 4) * (4x * 4x * 4 )
(16x * 4 ) * ( 16x *4)
16x * 16x = 256x
4 * 4 = 16
256x * 16
hope this helped a little
* = multiply
Idk what unit it is but it’s 80 cubic inches/feet/centimetres
