Which pair shows equivalent expressions?
Plz help me well mark brainliest! T-T

Option 3

Step-by-step explanation:

The first and second option can be eliminated immediately because the first equation simplified is:

2x + 10 = -2(x - 5)

2x + 10 = -2x + 10

The second equation expanded is:

-2(x + 5) = 2x - 10

-2x - 10 = 2x - 10

The third equation expanded is:

-2x - 10 = -2(x + 5)

-2x - 10 = -2x - 10

Meaning this equation is correct.

The fourth equation expanded is:

-2(x - 5) = -2x - 10

-2x + 10 = -2x - 10

Option 3 is the only correct option.

Hope this helps!

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."
