Answer:

Step-by-step explanation:

(3x+4)(x^2+px+5) \\=3x^3+3px^2+15x+4x^2+4px+20\\=3x^3+(3p+4)x^2+(15+4p)x +20

since we know that x^2  in this expansion is -23x^{2}

thus 3p+4=-23\\3p=-27\\p=-9

Hope that helps!

I need help -3x=x-(6-2x)?
USPshnik [31]
<span>Simplifying 3x + 6 = 2x
  Reorder the terms: 6 + 3x = 2x
  Solving 6 + 3x = 2x
  Solving for variable 'x'.
  Move all terms containing x to the left, all other terms to the right.
  Add '-2x' to each side of the equation. 6 + 3x + -2x = 2x + -2x
  Combine like terms: 3x + -2x = 1x 6 + 1x = 2x + -2x
  Combine like terms: 2x + -2x = 0 6 + 1x = 0
  Add '-6' to each side of the equation.
6 + -6 + 1x = 0 + -6
 Combine like terms: 6 + -6 = 0
 0 + 1x = 0 + -6 1x = 0 + -6
Combine like terms: 0 + -6 = -6 1x = -6
 Divide each side by '1'. x = -6
 Simplifying x = -6
</span>so the answer is x =-6

At the end of 10 basketball games, a teams mean score is 35 points per game. At the end of 11 games, their mean score has gone d
morpeh [17]

Their total points for the first 10 games were

(10) x (35) = 350 total .

Their total points after 11 games were

(11) x (33) = 363 total .

They must have scored (363 - 350) = 13 points in that 11th game.

I hate to say it, but these kids and their coach are in the wrong game.
