Need can’t figure it out! plz you y=x^2+2x y=3x+20

A. y = x^2 + 2x          B. y= 3x +20        Substitute 3x +20 for y in Equation A.

A. (3x + 20) = x^2 + 2x                           Set equation A up equal to 0 by

  -3x -20              -3x -20                    subtracting 3x and 20 from both sides.

A. 0 = x^2 - x -20                                   Factor the quadratic equation and solve.

A. 0 = (x - 5)(x + 4)

A. x - 5= 0    x + 4= 0

      +5   +5      -4      -4

A. x = 5, x = -4                                       Now substitute the values for x back                                into the equations to find the values for y, and your solutions

y = (5)^2 + 2(5)          y = 3(5) +20         y = (-4)^2 + 2(-4)          y = 3(-4) +20

y= 25 +10                  y = 15 +20            y = 16 + (-8)                  y = -12 +20

y = 35                         y = 35                  y = 8                             y = 8

the answer should be d) he was one of those young thousands who greeted the war with a certain amount of relief, welcoming the liberation from webs of tangled emotion" since it is the best option because it shows his desire to free himself. 

hope this answer you! have a great day.

dramatic irony occurs when the reader/audience knows more about a character's situation than the character does. the one main effect is that it gives the reader a sense of superiority, or detached superiority. the reader not only seemingly discovers what is revealed, but feels superior for doing so.
