Answer:
6.3 units (nearest tenth)
Step-by-step explanation:

Using the formula above,
distance between (-8, 6) and (-6, 0)
![=  \sqrt{ {[ - 8 - ( - 6)]}^{2}  +  {(6 - 0)}^{2} }](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%7B%20%7B%5B%20-%208%20-%20%28%20-%206%29%5D%7D%5E%7B2%7D%20%20%2B%20%20%7B%286%20-%200%29%7D%5E%7B2%7D%20%7D%20)




= 6.3 units (nearest tenth)
 
        
             
        
        
        
Answer:     
      
Step-by-step explanation:
Since, by the SAS formula of finding the area of triangle,
The area of triangle, 
Where,  and
 and   are adjacent sides and
 are adjacent sides and  is the included angle of these sides
  is the included angle of these sides
Here,  
  
 
And, 
Thus, the area of the triangle ABC, 



Therefore, Third Option is correct.

Answer:
x=39
y=14
Step-by-step explanation:
x+y=53...(1)
x-y=25...(2)
(1)+(2): 2x==78
x=78/2
x=39
then
x+y=53
39+y=53
y=53-39
y=14
 
        
             
        
        
        
In Polynomials all the exponents of x-variable must be positive integers, then polynomials are:
<span>a) -x^5+7x-1/2x^2+9, the exponents of x's are: 5, 1, and 2
b) x^3-4x-3, the exponents of x's are: 3, and 1
f) x^4+x^3√7+2x^2-√3/2x+π, the exponents of x's are: 4, 3, 2, and 1
Not polynomials are:
</span><span>c) 4 / x^2-4x+3 = 4x^(-2)-4x+3, the exponents of x's are -2, and 1
d) x^4+5/x^3-√x+8=x^4+5x^(-3)-x^(1/2)+8, the exponents of x's are 4, -3, and 1/2
e) </span>|x|^2+4√x-2=<span>|x|^2+4x^(1/2)-2, the exponents of x's are 2 and 1/2</span>
