Add.

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

-5x^4+6x^3-31+6x^5-x^2+12x | The full answer

Step-by-step explanation: When doing one of these problems that does not need you to solve for the value of _blank_ then all you need to do it add like terms. Remember that 5^2 + 5x cant be added, while 5x+5x can. only like terms work. If you need more practice look up some videos on this topic. Have a great day.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
