You can check whether this is true using Pythagoras' Theorem. The Pythagorean Theorem:
a² + b² = c², where c is the hypotenuse of a right triangle.
Let's plug in the given values and check the validity of the statement.
a² + b² = c²
7² + 9² = 11²
49 + 81 = 121
130 = 121
This is false. Thus,
Answer:
False - a triangle with side lengths 7, 9, and 11 is not a right triangle.

Answer:
PROBLEM 5: 80
PROBLEM 6: 94
Step-by-step explanation:
<u>PROBLEM 5:</u>
5(2 times 5 + 6)
=5(10+6)
5(16) = 5 times 16
=80
<u>PROBLEM 6:</u>
4 times(5 to the power 2)-6
4(25)-6
=100-6
=94
