The question reminds you of all the tools you need:
It says ...
"Opposite angles are equal."
So the upper right angle is x+40 just like the bottom left,
and the bottom right angle is 3x+20 just like the upper left.
And it says ...
"The sum of all angles is 360°."
You know what each of the four angles is, so you can addum all up,
set the sum equal to 360, find out what number ' x ' is, and then 
use that to find the size of every angle.

Answer:
To get the function <em>g</em>, shift <em>f </em>down by 8 units.
Step-by-step explanation:
The constant - 8  at the end of function g(x) suggests the parent function f(x) was translated 8 units down.
 
        
             
        
        
        
Answer:
12 pounds
Explanation:
If you were to divide 12.24 from 12 you would get 1.02, which would be the cost of each pound.
Meanwhile, if you were to divide 8.24 from 8 you would get 1.03, which would be the cost of each pound.
So although its only a 1 cent difference and you are technically spending more by buying the 12 pounds, if it were to buy 8 pounds from the cost of each pound for the 12 pounds, you'd only be spending $8.16 vs $8.24.
Because you would multiply 1.02, which is the cost of each pound for 12, by 8 and you would get 8.16.
