Answer:
A=L*W
Let w be width
L=(w+6)
40=(w+6)*w
40= w^{2} +6w
 w^{2} +6w-40=0
 w^{2}+10w-4w-40=0  
w(w+10)-4(w+10)=0
(w-4)(w+10)=0
w=4
Length= 10 units
Width=4 units

Answer:
4
Step-by-step explanation:
1/5 is the same as 2/10. How many 2's can you put in 9? You can put 4.5 2's in a 9. However, filling half a bag does not fill the entire bag, so the answer would be 4. You can fill 4 full 1/5 pound bags with 9/10 pounds of granola.

Given equation is  .
.
Now we need to find about what are the key aspects of the graph of  , where b is a real number.
, where b is a real number.
We know that square of any number is always positive. 
then  must be a positive number.
 must be a positive number.
So that means for any real number b, as the value of b increases then graph of f(x) shifts downward by  units as compared to the graph of parent function
 units as compared to the graph of parent function 
 
        
                    
             
        
        
        
Answer:
The probability that none of the LED light bulbs are defective is 0.7374.
Step-by-step explanation:
The complete question is:
What is the probability that none of the LED light bulbs are defective?
Solution:
Let the random variable <em>X</em> represent the number of defective LED light bulbs.
The probability of a LED light bulb being defective is, P (X) = <em>p</em> = 0.03.
A random sample of <em>n</em> = 10 LED light bulbs is selected.
The event of a specific LED light bulb being defective is independent of the other bulbs.
The random variable <em>X</em> thus follows a Binomial distribution with parameters <em>n</em> = 10 and <em>p</em> = 0.03.
The probability mass function of <em>X</em> is:

Compute the probability that none of the LED light bulbs are defective as follows:

                 
Thus, the probability that none of the LED light bulbs are defective is 0.7374.
