This is the associative property. Basically if you move the parenthesis either to left or right you’ll still get the right answer. So 4 times 5 equals 20 and 20 times 3 equals 60. 3 x 4 equals 12 and 12 x 5 equals 60

mezya [45]

Answer:

The friend's claim is not correct

Step-by-step explanation:

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal yo -1)

Example

A given line has a slope of $m_1=1/2$ ---> (is less than 1)

the slope of the line perpendicular to the given line is equal to

$m_1*m_2=-1$

substitute

$(1/2)*m_2=-1$

$m_2=-2$

the perpendicular line don't have a positive slope

therefore

The friend's claim is not correct
