Answer:

6x^5-5x^4+6x^3-x^2+12x+-31

Step-by-step explanation:

The question is to simplify (add) the expression shown below:

(-5x^4+6x^3-43)+(6x^5-x^2+12x+12)

<em>We can get rid of the parenthesis and add like terms:</em>

(-5x^4+6x^3-43)+(6x^5-x^2+12x+12)\\=-5x^4+6x^3-43+6x^5-x^2+12x+12\\=6x^5-5x^4+6x^3-x^2+12x+12-43\\=6x^5-5x^4+6x^3-x^2+12x+-31


<em>standard form means to keep the terms in descending order of powers, which is already shown.</em>

50 POINTS &amp; BRAINLIEST!!!! HELP ASAP!!!
Allisa [31]

6(2x - 11) + 15 = 21

First step use distributive property on the left side to remove the parenthesis, to do this multiply 6 by each term inside the parenthesis:

12x - 66 + 15 = 21

Second step, simplify the left side by combining the like terms:

12x - 51 = 21

Third step, add 51 to both sides of the equation:

12x = 72

Last step, divide both sides by 12:

x = 72/12

x = 6
