Answer:
38 cm
Step-by-step explanation:
The perimeter of a rectangle is given by
P =2(l+w)
P =2( 2x+1 + x)
Combine like terms
P = 2(3x+1)
Distribute
P = 6x+2
Let x=6
P = 6*6+2
= 36+2
= 38 centimeters
Answer:
42%
Step-by-step explanation:
x is for the volume of the container
the amount filled in the first container=0.30x
the volume of the first container + 50% of the second=(x+x*50%)=1.5 x
the amount of acid in the second container= 1.5x * 50%=0.75x
total amount of acid in the third one =0.3x+0.75x=1.05x
total solution : x+1.5x=2.5x
percentage=1.05x/2.5x= 0.42 or 42%
