Answer:
x=-8
Step-by-step explanation:
on squaring both sides
either x-2=0 or x+8=0
either x=2 or x=-8
Putting x=2 in original equation, we get
7=7 hence, it is not an extraneous solution
Putting x=-8 in original equation
i.e. 3=-3
Hence, x=-8 is an extraneous solution (since it doesn't satisfy the original equation)
The answer is C an example is 20% of $20 is 4, so you would lose the zero and double the 2 to get 4
The area is 19.5 and the perimeter is 23.1
Answer:
x = 3
Step-by-step explanation:
reverse foil the denominator and find the largest solution.
x-3(x+1)
3 is the largest solution
D. (x-14)(x+14)
a negative and a positive multiplied makes a negative outcome so -14•+14=-196. x•x is = to x^2
