Answer:
21x+4
Step-by-step explanation:
X’s: 21x
#’s: 4
So it will be 21x+4
Answer: Options a,b are correct
Explanation:
We can check the true statements with thye help of logarithmic rules
1. product rule log(xy) = logx+logy
2.quotient rule 
3. Exponent rule 
Option a is satisfying product rule
Option b is satisfying exponent rule
Option c is discarded because
not equal to p*LogM
Option D is discarded because logM-logN =
is not equal to log(M-N)
Hence, Option a and b are correct.
Answer: H
Step-by-step explanation:
Point C line CB line segment CA and ray CD
C

$12
If the cost c is at least $12 then it could be equal to 12, or could also be a cost greater than $12. So, c is greater than or equal to 12, expressed as <span>c

$12</span>
The apex If the triangle is 40, bc it's alternate interior with 40, due to the parallel lines.
Now all angles sum 180 in a triangle:
y+10 + 77 + 40 = 180
y + 127 = 180
y +137 -127 = 180-127
y = 53
Now the y+10 + 40 + x-1 sum to 180 2nd they all make a straight line:
x-1 + 40 + 53+10 = 180
x + 102 = 180
x + 102 -102 = 180-102
x = 78
Therefore the correct answer is:
B.) x = 78, y = 53
