Some one me with these questions answer any that you know are correct i cant risk any wrong answers 1. add. (−5x ^4 +6x^2−43)+(6x^4−x^2+12x+12) express the answer in standard form. enter your answer in the box 2. add (x^3-2x^2+4)+(2x^3 + x^2−2) express the answer in standard form. enter your answer in the box. 3.add (1+7x^3-x^2) + (x^3+2+2x^2) express the answer in standard form . enter your answer in the box

1) x⁴ + 5x² + 12x - 31

              2) 3x³  -  x²  + 2

              3) 8x³ + x² + 3

Step-by-step explanation:

1) Line up like terms and add the coefficients of each term

 -5x⁴ + 6x²          - 43

+ 6x⁴ -  1x² + 12x + 12

    x⁴ + 5x² + 12x - 31

2) Line up like terms and add the coefficients of each term

   1x³ - 2x² + 4

+ 2x³ + 1x²  - 2

  3x³  -  x²  + 2

3) Line up like terms and add the coefficients of each term

   7x³  - 1x² + 1

+ 1x³ + 2x² + 2

   8x³ + x² + 3

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
