Marissa subtracted a negative number from a positive number. Her result was negative. Is that reasonable? Explain

Desmond wants to sell his car that he paid $8,000 for 2 years ago. the car depreciated, or decreased in value, at a constant rate each month over a 2-year period. if x represents the monthly depreciation amount, which expression shows how much desmond can sell his car for today? 8,000 + 24x 8,000 − 24x 8,000 + 2x 8,000 − 2x

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9
