Subtract (7x^5-12x^2y+33y^2) from (5x^5-5x^2y+9y^2) simplify your results:
hoa [83]

Answer:

<em>- 2 </em>x^{5}<em> + 7x²y - 24y² </em>

Step-by-step explanation:

( 5 x^{5} - 5x²y + 9y² ) - ( 7 x^{5}  - 12x²y + 33y² ) =

5 x^{5} - 5x²y + 9y² -  7 x^{5}  + 12x²y - 33y² =

( 5 x^{5} - 7 x^{5} ) + ( - 5x²y + 12x²y ) + ( 9y² - 33y² ) =

<em>- 2 </em>x^{5}<em> + 7x²y - 24y²</em>

In a board game, the player who makes the last move receives a 12-point bonus for ending the game.
Reika [66]

Answer:

f(s) = 2( 5s + 6)

Step-by-step explanation:

This means value of f of s

final score before bonus = 2 x 5 = 10

Add the bonus = 2 x 6 = 12

Add together if simplified= 10s+12, we remove the s, then add and confirm score has now been fully totaled = 22.

Half way through we can show 10s is the score of both even and only fs = 22 for the winner.
