Answer:

Option (A)

Step-by-step explanation:

2x² + 5x - 8 = \frac{5}{2}x + 20

2(2x² + 5x - 8) = 2(\frac{5}{2}x+20)

4x² + 10x - 16 = 5x + 40

4x² + 10x - 5x - 16 - 40 = 0

4x² + 5x - 56 = 0

By using graphing calculator,

x - intercepts are,

x = -4.4 and x = 3.2

Therefore, Option (A) will be the correct option.

Elanso [62]

Answer:

-18.

Step-by-step explanation:

They're both negative numbers being added to each other, so you'd add 6 and 12 (which is 18) and then put a negative sign before the 18. Therefore, your answer is -18.
