Answer:
x^3+3x^2+4x+5
Step-by-step explanation:
Ok, so what helps me solve this kind of problem is to circle, underline, or box the like terms(the ones with the same exponent and variable). Be sure to note the sign of each term when combining like terms. take it one step at a time, and work downwards starting with the highest exponent. You have -x^3 and +2x^3, which is x^3. Next, you have +2x^2 and +x^2, which is 3x^2. You should write down each of these as you go, so you should now have x^3+3x^2. Then combine the terms with no exponent but with x, which is 5x and -1x, which is +4x. You should have x^3+3x^2+4x now. Lastly, just combine the numbers 1, -1, and 5, which is 5. This gives you an answer of x^3+3x^2+4x+5.

Answer:
The cost for 5 songs is $5.35
Step-by-step explanation:
Find the unit rate for 1 song by dividing the total cost for 3 songs by 3
$3.21 ÷ 3 = $1.07
The unit rate is $1.07 per song, so multiply that by 5 to find the total cost for 5 songs
$1.07 * 5 = $5.35
