How to solve this showing all work ! Also explain why they aren’t polynomials if you can :)
Lesechka [4]

Polynomials are linear combinations of positive integer powers. For example,

x^{100}+30x^2-\sqrt 2\,x+21

is a polynomial, but

-x^{-1}-4x^\pi+x^{3/2}

is not.

(In case you're unfamiliar with the term, a linear combination of two quantities is the sum of scaled versions of those quantities, e.g. a general linear combination of a and b is k_1a+k_2b, where k_1,k_2 are any numbers.)

8x^2-18\sqrt x+5x-3 is not a polynomial; the offending term is -18\sqrt x, or -18x^{1/2}.

Which expression is equivalent to 8(k + m) - 15(2k + 5m)?<br> agul
SpyIntel [72]

Answer:

-22k - 67m

Step-by-step explanation:

You have to use the Distributive property:

8(k + m) - 15 (2k + 5m)

8k + 8m - 30k - 75m

Now simplify:

8k - 30k + 8m - 75m

-22k - 67m

Be careful with positives and negatives!

Hope this help!

During a film festival, the first film ticket is priced at 16 dollars, and each additional ticket is 11 dollars. If rico spend 7
MrMuchimi

Answer:

He purchases a total of 6 tickets:  $16 for the first and $5 each for 5 more tickets.

Step-by-step explanation:

Here we need an equation with a constant term and a variable term:

$71 total = $16 + ($11/ticket)*(t tickets)

Subtracting $16 from both sides, we get

$55 +  ($11/ticket)*(t tickets)

Dividing both sides by ($11/ticket)

results in

$55

-------------- = 5 tickets (beyond the first one)

$11/ticket
