2 wrong 3 right because you might added wrong
X^2 + 2 = x + 8
x^2 - x + 2 - 8 = 0
x^2 - x - 6 = 0
Input 1 => 1^2 - 1 - 6 = 1 - 1 - 6 = -6
Input 3 => 3^2 - 3 - 6 = 9 - 3 - 6 = 0
Input 4 => 4^2 - 4 - 6 = 16 - 4 - 6 = 6
Input 5 => 5^2 - 5 - 6 = 25 - 5 - 6 = 14
Solution set { -6, 0, 6, 14}
Answer:
1a) 1141/660
3/5 + 6/11 +7/12
find the LCM of the denominators
the LCM of 5,11,12 is 660
after finding the LCM divide it with the denominator.
after dividing 660 by 5 i get 132. So i need to multiply it with 3. Now, i got 396. Do the same with the rest of the numbers.
u will get smth like this: 396+360+385/660
and the final answer will be1141/660.
b) 71/40
c) 211/28
d) 103/20
Answer:
The answer is "triangle ABC is not a right triangle".
Step-by-step explanation:
For a right-angle triangle:
Its square upon on longest or triangular edges is equivalent to the total of the other two squares
Its parameters indicated throughout the question are;
Square of lateral length 
The square of lateral length 
The square of lateral length 
Thus, the longest side is C, as well as the size 
of the squares of its two sides, is
, lower than square 
, hence, the ABC triangle is not correct. Its longest edge is consequently C.
