Find a counterexample to disprove each statement, or support it with four examples.
31. All triangles have three congruent angles.
32. If p is an even number, then p + 12 is even.

25

Step-by-step explanation:

Given  : If a = 2 and b = 4, then 27 - b^2 ÷ a + (11 - 5)

To find : Solve it.

Solution : We have given

27 - b² ÷ a + (11 - 5).

Plug a = 2, b= 4.

27 - 4² ÷ 2 + (11 - 5).

Now we solve the parenthesis

27 - 4² ÷ 2 + 6.

Now, we solve the square.

27 - 16 ÷ 2 + 6

Now we solve divide

27 - 8 +6.

19 + 6.

25.

Therefore, 25.
