Answer:
17
Step-by-step explanation:
The first thing to do is plug in the numbers for the equation. Starting with:
[-20-(-3)]/(19-20)
When you answer that you simplify the answer to
(-20+3)/(19-20)
You answer what is in the parenthesis first.
(-17)/(-1)
After this step you simplify.
17.
The answer is seventeen because any number over 1 is just the number. For example, 3/1=3. The answer is positive because the negative in the numerator and denominator cancel eachother out. leaving the answer as 17.
 
        
                    
             
        
        
        
Answer:
The scaled surface area of a square pyramid to the original surface area.
The scaled area of a triangle to the original area.
Step-by-step explanation:
Suppose that we have a cube with sidelength M.
if we rescale this measure with a scale factor 8, we get 8*M
Now, if previously the area of one side was of order M^2, with the rescaled measure the area will be something like (8*M)^2 = 64*M^2
This means that the ratio of the surfaces/areas will be 64.
(and will be the same for a pyramid, a rectangle, etc)
Then the correct options will be the ones related to surfaces, that are:
The scaled surface area of a square pyramid to the original surface area.
The scaled area of a triangle to the original area.

Answer:
x-9
Step-by-step explanation:
"Less than" switches the way of the expression.
If the "less than" was not there it would have been: 
9-x
"Less" means subtract so you would subtract x from 9.
Hope this helped!
