1. A polynomial means it has more than one term. 
   a. has 4 terms
   b. has 1 term (not a POLYnomial)
   c. has 3 terms
   d. has 2 terms
2. The first word in a polynomial description tells the degree (max amount of exponents) of the expression, and the second word tells how many terms it has.
   a. This answer means it's maxed exponent is to the fourth power, which it's not. (WRONG)
   b. This answer means that it has a max exponent to the third power, which is true, and it also says it has three terms, which is also true. (CORRECT)
3. You must combine like terms in this polynomial.
=> 14x^2 - 6x^2 =8x^2
=> 5x + 2x = 7x
=> -8
   d. This answer combines all the terms correctly.
4. To simplify this equation, you must first distribute the negative to all of the second equation.
(4x^2 -3x+2) + (-2x^2-5x+7)
Now, combine like terms.
=>4x^2 - 2x^2 = 2x^2
=>-3x - 5x = -8x
=>2 + 7 = 9
   d. This answer simplifies it correctly

How did i work this out?
bogdanovich [222]

knowing the answer is between 3 & 4 plug those as x and see what you get for answers than adjust the number accordingly

3^3+2(3) = 33 so its higher than 3

4^3 + 2(4) = 72 so it is lower than 4

try the middle so try 3.5

3.5^3 + 2(3.5) = 49.875

question states use 1 decimal place so now try 3.6

3.6^3+2(3.6) = 53.856


3.5 is closest

Give the equation of the horizontal asymptote shown below.
Oxana [17]
Polynomial division yields

\dfrac{7x^2}{x^2+5}=7-\dfrac{35}{x^2+5}

As x\to\pm\infty, you have the remainder term approaching 0, so the horizontal asymptote is the line y=7.

alaina owes her mom $15 and her friend $27. then she babysat and earned $35. how much more money does alaina need to earn in ord
tino4ka555 [31]

35 - 27 = 8

15 - 8 = 7

She just payed off her best friend and has $8 left.

So she needs to earn $7 more to pay off the $15 she owes her mom
