Answer:

  c)  (-2, 6)

Step-by-step explanation:

Subtracting the second equation from the first gives ...

  (y) -(y) = (x^2 +3x +8) -(2x +10)

  0 = x^2 +x -2 . . . . . simplify

  0 = (x -1)(x +2) . . . . factor

Solutions for x are 1 and -2. The corresponding y-values are ...

  y = 2{1, -2} +10 = {2, -4} +10 = {12, 6}

The solutions are (1, 12) and (-2, 6). The only matching choice is (-2, 6).

Answer:75

Step-by-step explanation: Find the area of the triangle which is 1/2 base times height. The base is 9 while the height is 4+5+1 which is 10. 10 times 9 is 90 and half of 90 is 45. Then find the area of the rectangle which is length times width which is 5 times 3 which is 15. Then subtract 15 from 90 which gets you the answer 75.
