Answer:

only -7

Step-by-step explanation:

Just plug them in.

so for x=-7 \sqrt{-2(-7)-5}=(-7)+4\\\sqrt{9}=-3 \\ 3=-3So this one is extraneous

Then if you plug -3 in you get 1 = 1 so this one is not extraneous.  if you need me to work this one out let me know.

If a = -8, b = -7, c = 6, then verify that (a+b) + c = a+ (b+c)<br><br> tysm for de help ✨
NISA [10]

The given information is,

→ a = -8

→ b = -7

→ c = 6

Let's verify the problem,

→ (a+b) + c = a+ (b+c)

→ (-8 - 7) + 6 = -8 + (-7 + 6)

→ -15 + 6 = -8 - 1

→ -9 = -9

→ [ LHS = RHS ]

Hence, it is equal and verified.
