18b-45 is an equivalent expression.
Answer:
38 cm
Step-by-step explanation:
R=red
blue=b
g=green
r+g+b=33
r=4g
b=g/2
we must convert to a common unit which could be the smallest unit so we must convert to blue
b=g/2 or g=2b
r=4g
r=4(2b)
r=8b
r=8b
g=2b
b=b
r+g+b=33=8b+2b+b=11b
11b=33
divide both sides by 11
b=3
g=2b
g=2(3)
g=6
r=8b
r=8(3)
r=24
r=24
g=6
b=3
