Answer:
184
Step-by-step explanation:
The sqrt(144) = 12
14^2 = 196
196 - 12 - 184
 
        
             
        
        
        
Answer:
cos F = adjacent/hypotenuse
= 15/28
 
        
             
        
        
        
To solve the problem posed in the statement we need to know the equivalence between squared foot and squared inches, and that is:
1 square foot = 144 square inches
So Reed uses 8 pieces of glass per 144 squared inches as well.
Now we can use a rule of three, simple and direct proportion to solve the question, it goes like this:
144 squared inches ------> 8 pieces glass
864 squared inches ------> x
x = (864)(8)/144
x = 48
Hence, Reed will use 48 pieces of glass to make a window that is 864 square inches.

Answer:
A. -4 + 6i
Step-by-step explanation:
Cause as we can see... (-2 - 2i)+(10-4i)
 We get when we multiply 2x2=4i
Next 10-4=6
Hope it helped u
