Each room has 2 walls that are 4x10 = 40 square feet and 2 walls that are 8x10 = 80 square feet. So 80+80+40+40 = 240 square feet of wall will be painted per room.
We use 2 coats of paint so in effect, we double the area. Imagine laying one thin wall on top of the other. The amount of paint area used per room doubles from 240 to 480
There are 4 of these rooms so 4*480 = 1920
The total area we need to paint is 1920 square feet
Divide this over 32 to get 1920/32 = 60
Final Answer: 60
Ratios between their corresponding edge lengths is B, false
Answer:
She didn't do the multiplication of 7 times the fraction 5/8 by using distributive property.
so the correct answer is the one that looks like:
Seven was not multiplied by StartFraction 5 over 8 EndFraction.
in your list of options.
Step-by-step explanation:
If one has a stack of seven books each 
thick, one should first convert the mixed number to an addition of an integer plus a fraction
as she did, and then multiply 7 by the addition, making sure to use distributive property and multiply both terms:
and she didn't do the multiplication of 7 times the fraction 5/8

Step-by-step explanation:
r≈0.56
a is the surface area is 4
Step-by-step explanation:
-16 + 3n = - 8 - 5n
Bringing like terms on one side
3n + 5n = - 8 + 16
8n = 8
n = 8/8
N = 1
