Answer: The multiplication property of equality is used to transform the equation from the first step to the second step.
Explanation:
The multiplication property states that if any number is multiplied both side of a equation the equation doesn't change.
If x = y and we multiply both side by m, then xm = ym is equivalent to x = y.
The given expression is,
Use multiplication property of equality, multiply 5 both sides,
Therefore, the multiplication property of equality is used to transform the equation from the first step to the second step.
A²+b²=c²
The hypotenuse of the triangle is c. (the slanted line, if it is a right triangle)
Simply fill in the variables, square them, and solve for the missing number.
Check out the picture, it is just an example.
Don't forget: the variable you are finding needs to be squared, that means that when you find your answer, find the square root of it.
