Given two numbers A and B, the commutative property of addition says:
A+B=B+A
Therefore:
9+8=8+9=17
Answer: Find answer in the attached files
Step-by-step explanation:
Answer:
A solution to a system of equations is a set of values for the variable that satisfy all the equations simultaneously. In order to solve a system of equations, one must find all the sets of values of the variables that constitutes solutions of the system.
Step-by-step explanation:
Answer:
Scalene and obtuse
Step-by-step explanation:
The triangle is scalene because all the sides are not equal, and it is obtuse because the central angle is greater than 90 degrees.
Answer:
square of longest side ≠ the sum of the squares of the other two sides
It's not a right triangle
Step-by-step explanation:
The converse of the Pythagorean Theorem is: If the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.
square of longest side: 12 12² = 144
the sum of the squares of the other two sides: 8² + 10² = 164
