Because of the Absolute Values, when x = -1 or -2, the overall range
is [-1, co)
Really simple. Divide by 2 then add and subtract 9
68/2 = 34
34 + 9 = 43
34 - 9 = 25
43 - 25 = 18
The two numbers are 43 and 25
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
A hexagon. 1/3 fits into 2 6 times, so that means there are 6 sides.
