We know that: 
We multiply the both terms i.e. f(x) and g(x) to get our answer.

So, we get 
Answer:

Step-by-step explanation:
<u>Given the two co-ordinates:</u>
A(x1,y1) = (-4,-8)
B(x2,y2) = (-4,0)
<u>Putting them in the distance formula:</u>
![|AB| = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\\|AB| = \sqrt{(-4-(-4))^2+(0-(-8))^2} \\\\|AB| = \sqrt{(-4+4)^2+(0+8)^2} \\\\|AB| = \sqrt{8^2} \\\\|AB| = 8\ units\\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=%7CAB%7C%20%3D%20%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D%20%5C%5C%5C%5C%7CAB%7C%20%3D%20%5Csqrt%7B%28-4-%28-4%29%29%5E2%2B%280-%28-8%29%29%5E2%7D%20%5C%5C%5C%5C%7CAB%7C%20%3D%20%5Csqrt%7B%28-4%2B4%29%5E2%2B%280%2B8%29%5E2%7D%20%5C%5C%5C%5C%7CAB%7C%20%3D%20%5Csqrt%7B8%5E2%7D%20%5C%5C%5C%5C%7CAB%7C%20%3D%208%5C%20units%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)

Answer:
20 X 1/20 = 1
10 X 1/10 = 1
Step-by-step explanation:
I hope that helps.
Solve for x over the real numbers:
5 x^2 - 21 = 10 x
Subtract 10 x from both sides:
5 x^2 - 10 x - 21 = 0
Divide both sides by 5:
x^2 - 2 x - 21/5 = 0
Add 21/5 to both sides:
x^2 - 2 x = 21/5
Add 1 to both sides:
x^2 - 2 x + 1 = 26/5
Write the left hand side as a square:
(x - 1)^2 = 26/5
Take the square root of both sides:
x - 1 = sqrt(26/5) or x - 1 = -sqrt(26/5)
Add 1 to both sides:
x = 1 + sqrt(26/5) or x - 1 = -sqrt(26/5)
Add 1 to both sides:
Answer: x = 1 + sqrt(26/5) or x = 1 - sqrt(26/5)
First one
why?? because i is just like a mirror it is reflected on the other side
