Answer:
Jaw saw an average of 6 birds each day
Step-by-step explanation:
Given: One day, Jean saw 7 birds. The next day, she  saw 11 birds. The next day, she saw no birds.
To find: average number  of birds Jean saw each day
Solution:
Average is a central value of a set of terms.
Average of terms  is given by
 is given by 
Number of birds, Jean saw on day one  = 7
 = 7
Number of birds, Jean saw on the second one  = 7
  = 7
Number of birds, Jean saw on the third one  = 7
 = 7
So,
average number  of birds Jean saw each day = 
Therefore,
Jaw saw an average of 6 birds each day
 
        
             
        
        
        
Answer:
x=13
Step-by-step explanation:
you have to isolate the variable
3(x-4)=x+14
distribute
3x-12=x+14
subtract 14 from each side
3x-26=x
subtract 3x from each side
-26=-2x
divide each side by -2
13=x
flip sides
x=13
hope this helps!!! :)

ANSWER : (9u - 8)2
STEPS:
Step-1 : Multiply the coefficient of the first term by the constant 81 • 64 = 5184 
Step-2 : Find two factors of 5184 whose sum equals the coefficient of the middle term, which is -144 .
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -72 and -72 
 81u2 - 72u - 72u - 64
Step-4 : Add up the first 2 terms, pulling out like factors :
 9u • (9u-8)
Step-5 : Add up the four terms of step 4 :
 (9u-8) • (9u-8)
 Which is the desired factorization
