- 1. A rectangular yard has a length 3x + 2 and a width 5x - 2. What is a simplified expression for its perimeter? (In your work you must show a diagram and work)
Outcome B8
A) Perimeter = 16x
B) Perimeter = -16x
C) Perimeter = 16x + 44
D) Perimeter = 15x2 + 4x - 4
E) Perimeter = 15x2 - 4
- 2. A soccer field has the dimensions 3x + 10 (length) and 2x + 1 (width). Find a simplied expression for the area of the soccer field as well as the result.
Outcome B9
A) Area = (2x + 1)(3x + 10) = 5x2 + 9x + 10
B) Area = (3x + 10)(2x + 1) = 6x2 + 23x - 9
C) Area = (3x + 10)(2x + 1) = 6x2 + 23x + 10
D) Area = (3x + 10)(2x + 1) = 6x2 + 20x + 11
E) Area = (2x - 1)(3x + 10) = 5x2 + 9x + 9
- 3. Evaluate: (6h3 - 9h2 + 15h) divide by 3h.

Outcome B10
A) 49
B) -15
C) 29
D) 20
E) 25
