Answer:
x = 1.47  or x = -7.47
Step-by-step explanation:
x²+6x+9=20
This is a quadratic equation
x²+6x+9-20=0
x²+6x-11=0
Step 1 : Write the quadratic formula
x = <u>-b±√b²-4(a)(c)</u>
               2a
Step 2 : Substitute values in the formula
a = 1
b = 6
c = -11
x = <u>-6±√6²-4(1)(-11)</u>
               2(1)
x = <u>-6±√80</u>
           2
x = -3 + 2√5 or x = -3 - 2√5
x = 1.47         or x = -7.47

Answer and Step-by-step explanation:
We see that the bottom two lines are parallel, which makes angle x and angle 5 "same-side corresponding angles". By definition, same-side corresponding angles are congruent. That means angle x = angle 5.
Note that you didn't provide any measures, so it is impossible to actually figure out an exact degree. However, angle x is the same degree as angle 5.
Hope this helps!
 
        
                    
             
        
        
        
Answer:
54.4311
Step-by-step explanation:
 divide the mass value by 2.205 (unit of conversion) :)
 
        
                    
             
        
        
        
So what you need to do is find the less he can use.
        
             
        
        
        
Answer:
