The answer is x² + 23x + 49
The area (A) of the shaded region is the difference between the area of the rectangle (A1) and the white square (A2).
A = A1 - A2
A1 = (x + 10)(2x + 5)
= 2x² + 5x + 20x + 50
= 2x² + 25x + 50
A2 = (x +1 )² = x² + 2x + 1
A = A1 - A2
= 2x² + 25x + 50 - (x² + 2x + 1)
= 2x² + 25x + 50 - x² - 2x - 1
= x² + 23x + 49

35 every week. 3 weeks would be 105, hours, enough to pay his sister back, leaving us with 40. 14 weeks later and he has 490, plus the 40, is enough to buy the bike. 17 weeks in total. The way i would write it is (530+65) divided by 35 is 17
