The total cost without the discount is given by:
  $
$
 Then, to find the discounted amount, we make the following rule of three:
 10 $ ------------------> 100%
 x ----------------------> 20%
 From here, we clear the value of x.
 We have then:

Answer: c
given volume is 125 cc
cube root of 125 is 5
aka 5×5×5=125
and 6×5×5=150
hence answer is c
        
             
        
        
        
Answer:
131ft is the amount of fencing material needed
Step-by-step explanation:
Perimeter is the distance around a shape: we have to sum all the distances
P = d1 + d2 + d3
P = 34 ft + 30 ft + 67 ft = 131 ft
 
        
                    
             
        
        
        
Since x co-ordinates are constant, answer has to be difference in y co ordinates therefore the answer is 4
        
                    
             
        
        
        
Answer:
v = 7
 is the value for which
x = (-21 - √301)/10
is a solution to the quadratic equation 
5x² + 21x + v = 0
Step-by-step explanation:
Given that 
x = (-21 - √301)/10 .....................(1)
is a root of the quadratic equation
 5x² + 21x + v = 0 ........................(2)
We want to find the value of v foe which the equation is true. 
Consider the quadratic formula 
x = [-b ± √(b² - 4av)]/2a ..................(3)
Comparing (3) with (2), notice that
b = 21
2a = 10
=> a = 10/2 = 5
and 
b² - 4av = 301
=> 21² - 4(5)v = 301
-20v = 301 - 441
-20v = -140
v = -140/(-20)
v = 7
That is a = 5, b = 21, and v = 7
The equation is then 
5x² + 21x + 7 = 0
