Answer: I think its BC and DC I dont know But I hope this helps!
Step-by-step explanation:
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)
An equation typically has a slope. Since there is no equation given, I am assuming that 1/7 is the slope:)
1/7 simplified into decimal form is is 0.1428!
