Answer:
Given sides 12, 16 and 20 can be the sides of right triangle.
Step-by-step explanation:
Sides of right triangle always follow the Pythagoras theorem.
i.e 
For the given Lengths 7, 40 and 41
We need to check if


That means, 
hence 7,40 and 41 can not be the sides of right triangle.
Next,
Given sides 12,16 and 20.
Again follow the similar process used in the above problem.

Therefore given sides 12,16 and 20 can be the sides of right triangle.

Step-by-step explanation:
Your answer
Proportion????
So, cost = width
If width is 80 then cost will be 48
I dont know if this right.
Answer accurancy 80%
Mark it as Brainlist answer. Follow me.
1st you're going to want to divide the figures into smaller parts. I deviated them and got the measurements 2W, 1L, and 2H. The formula for rectangular prisms is LxWxH and I got 4.
Now we need to use the same formula for the other figure.
4L, 2W, and 1H.
Multiple them all and we get 8
Now we take the Volume of both the figures and add them together 8+4 = 12
So, the volume of the composite figure is 12
Answer: Jamar is correct
Step-by-step explanation:
Integer is a number that is a whole number and can either be positive or negative but it can't be a fraction or decimal. e.g 4, -2, 6, -23 etc.
A whole numbers are zero and other natural numbers such as 1, 4, 23. Negative numbers are not part of whole numbers.
From the statement made in the question, Sophia is wrong while Jamar is correct. The numbers aren't all whole numbers because some are negative.
Multiply 72×80 or 8. (I'm not sure of its 8 or 80).HOPE THIS HELPS YOU:)
