4. 9 is not the base nor the height of the triangle
1. Triangle ABC is shown below. If AC = 9 cm, which of the following is closest to the area of the triangle? A C B 9
This is a triangle problem! x x
Now use your formula:
A = ½ bh
When given the hypotenuse (x√2), you must divide by √2 to get back to x.

A 13 cm2
You used √3 instead of √2!
B 41 cm2
9 is not the base nor the height of the triangle
C 20 cm2
Correct Answer!!!!
D 81 cm2
When given the hypotenuse, divide by √2, not multiply

5. Substituted in the 3 and 5 backwards
2. If x ʘ y = 3x + 2y – xy, what is the value of 3 ʘ 5?
If x ʘ y = 3x + 2y – xy, then 3 ʘ 5 = 3(3) + 2(5) – 3(5)
This is a different type of problem. Instead of using normal operation symbols (like +, -, or ∕ ) a “new” operation symbol will be made up. Carefully substitute the values from x and y into the problem.
