<u>ANSWER:  </u>
x-intercepts of  
<u>SOLUTION:</u>
Given,  -- eqn 1
 -- eqn 1
x-intercepts of the function are the points where function touches the x-axis, which means they are zeroes of the function.
Now, let us find the zeroes using quadratic formula for f(x) = 0.

Here, for (1) a = 1, b= 12 and c = 24 


Hence the x-intercepts of  
 
        
             
        
        
        
Answer:
it 180 degree try to add them all the subtract with 180 and that equals x

Answer: y=5x+3
Step by step explanation: 
Perpendicular meaning that the product of the slope/gradient is -1 hence ...
-1/5 * x = -1 
x = -1/-1/5
x = 5 
The equation perpendicular to y=-1/5x-3 is y=5x-c 
Now it contains the points (1,2) 
x variable is 1 and y variable is 2 plug them into the line equation 
2=5(1)-c 
2=5-c
2-5=-c
-3=-c divide by -1
3=c 
Hence the perpendicular equation is y=5x+3 
Hopefully it’s correct :) 
        
             
        
        
        
Answer:
y=4/3x+2
Step-by-step explanation:
y=mx+b
b is y intercept, and in this case, 2
m is the slope, and in this case, 4/3
Hope this answers your question.
 
        
                    
             
        
        
        
Answer:
62.4 square centimeters
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The surface area of the triangular pyramid is equal to the area of the triangular base plus the area of its three lateral triangular faces
In this problem the triangles are equilateral, that means, the 
surface area is equal to the area of four congruent equilateral triangles
so
![A=4[\frac{1}{2}(b)(h)]](https://tex.z-dn.net/?f=A%3D4%5B%5Cfrac%7B1%7D%7B2%7D%28b%29%28h%29%5D)
we have

substitute
![A=4[\frac{1}{2}(6)(5.2)]=62.4\ cm^2](https://tex.z-dn.net/?f=A%3D4%5B%5Cfrac%7B1%7D%7B2%7D%286%29%285.2%29%5D%3D62.4%5C%20cm%5E2)
