This question is saying that all the dimension of the statue are multiplied by a certain value in order to get to the scaled dimensions.
We can do 6/18 to find the scale value to be 1/3
-1.25 is the answer in decimal form
-4(2^3)/2+17
Step 1: do what is in the parenthesis which is two to the square root of three
Step 2: Which then u multiply it which the answer would be 8
Step 3: then you take the -4 and the 8 and you will get -32
Step 4: then you divide -32 and 2 and get -16
step 5; thenget -16 and add 17 which you will get the answer 1
You do this so that you can find the factors of the original equation of a^2 - b^2
