Since the triangle is isosceles the measure of angle B is also 47. 
since you have dropped a perpendicular bisector the measure of angle x is 90. and since the angles must add to 180 you get 47+47+a=180 and a= 86. since y is half this we have y is 43

39x^3 = 13*3*x*x*x
-6x^2 = 2*3*x*x*-1
-3x    = 3*x*-1
so in all these factorizations, 3*x is common. so 3x is the common factor.
by seperating the common factor,
3x(13x^2 - 2x-1)
will be the factorization.
   xy + 5x - 5y - 25
=x (y+5) -5 (y+5)
=(x-5) (y+5)
hope I helped ya!!!

Answer:
6
9
6.48
Step-by-step explanation:
this is the easiest way to solve for percentage:
 Where all the percents (except 100) would go in part
  Where all the percents (except 100) would go in part 
and the whole number would go in whole 
 Then multiply 24 × 25 ÷ 100 = 6
  Then multiply 24 × 25 ÷ 100 = 6 
 Multiply 60 by 25 then divided by 100 = 9
  Multiply 60 by 25 then divided by 100 = 9
Then for the last one 9 is what percent of 72
all we have to do is multiply 9 and then convert 72 into a decimal (0.72)
Then 9 × 0.72 = 6.48
 
        
             
        
        
        
Answer: 1760
Step-by-step explanation:
Cost of 1 flyer = $0.25 or 25 cents
Budget is = $555
Let us assume that supplies cost is a one time cost
Cost of supplies for one time = $115
So budget remains = 
So in $0.25 we get = 1 flyer
In $440 we get =  = 1760
Hence, we can buy 1760 flyers.
hope this helped
