So will be choice D.
bc. 5/6 = 10/12 = 2*5/2*6 = 5/6
Answer:
x = 9
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
=
( cross- multiply )
12(x - 1) = 96 ( divide both sides by 12 )
x - 1 - 8 ( add 1 to both sides )
x = 9
I think x= -7 because 4x7=28
No its sss because you have no given angles only sides
5 m/sec or 300m / min
using speed = 
change 5 min 20 sec to seconds = (5 × 60) + 20 = 320 sec
speed =
= 5m / second or
speed = 60 × 5 = 300m / minute
