Find the ratio of a:b:c in the simplest form.
a: b = 2:9 and b: c = 2 : 3

a : b : c = 4 : 18 : 27

Step-by-step explanation:

a: b = 2:9 and b: c = 2 : 3

a : b = 2*2 : 9*2 = 4 : 18

b : c = 2*9 : 3*9 = 18 : 27

a : b : c = 4 : 18 : 27

40 minutes

step-by-step explanation:

add the time and multiply by 2

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
