Sorry but this isnt even a full question.......
        
             
        
        
        
Good morning ☕️
Step-by-step explanation:
11+y is an expression that contains a variable ‘y’ 
then its value depends on ’y’
examples :
if y = 0 → 11+y = 11+0 = 11
if y = 1 → 11+y = 11+1 = 12
if y = 2 → 11+y = 11+2 = 13
and so on.

Answer: 
Step-by-step explanation:
 A line that cuts a circle at two points is called "secant".
 There is a theorem known as "Intersecting Secant Theorem". This is the theorem you need to use to find the value of "d".
 According the Intersecting Secant Theorem:
 
 Having this expression, the next step is to solve for "d":
 Use Distributive property:
 
 Subtract 256 from both sides:
 
 
 Divide both sides by 16:
 
 The value of "d" rounded to the nearest tenth is:
 
 
        
             
        
        
        
If you would like to solve - 3 * a^2 - b^3 + 3 * c^2 - 2 * b^3, if a = 2, b = -1, c = 3, you can calculate this using the following steps:
a = 2, b = -1, c = 3
- 3 * a^2 - b^3 + 3 * c^2 - 2 * b^3 = - 3 * 2^2 - (-1)^3 + 3 * 3^2 - 2 * (-1)^3 = - 3 * 4 - (-1) + 3 * 9 - 2 * (-1) = - 12 + 1 + 27 + 2 = 18
The correct result would be 18.
