Answer:

  • C) -582°

Step-by-step explanation:

Coterminal angles sum to 360°n, where n is an integer.

Given angle is 138°

<u>The difference is:</u>

  • A) 438° - 138° = 300°, no
  • B) -136° - 138° = -274°, no
  • C) -582° - 138° = -720° = -2(360°), yes
  • D) 228° - 138° = 90°, no

what algebraic expression must be added to the sum of 3x squared + 4x + 8 and 2x squared -6x + 3 to give 9x squared -2x - 5 as t
gregori [183]
<span>3x^2 + 4x + 8 + 2x^2 - 6x + 3 to give result as 9x^2 -2x - 5


</span>3x^2 + 4x + 8 + 2x^2 - 6x + 3 
= 5x^2 - 2x + 11

so

9x^2 -2x - 5 - (5x^2 - 2x + 11)
= 9x^2 -2x - 5 -  5x^2 +  2x - 11
= 4x^2 -16

answer

expression (4x^2 -16) must be added to the sum of (3x^2 + 4x + 8) and (2x^2 - 6x + 3) to give the result as (9x^2 - 2x - 5)
