- Slope Formula:

So remember that <u>perpendicular lines have slopes that are negative reciprocals to each other</u> and <u>parallel lines have the same slope.</u> To find out if they are either parallel or perpendicular, plug the pair of points into the slope formula to find their slopes:

Since these slopes aren't the same nor are they negative reciprocals to each other, <u>the lines are neither parallel nor perpendicular.</u>
-10 = -10 + 7m
Add 10 to each side: 0 = 7m
Divide each side by 7 : 0 = m
Please take a second and just LOOK at the equation you started with.
It says:
-- You have this number '-10' .
-- Your number -10 is going to be exactly the same size
after you add 7 of something to it.
The ONLY way that could happen is if the 'something' is 'nothing' .
' m ' must be nothing.
Answer:
Step-by-step explanation:
It can be shown that all four sides of this figure have the same length. This, in turn, is the definition of a rhombus.
The factors of 25 and 60 would be 5. 25 divided by 5 is 5 and 60 divided by 5 is 12.
So here is what the distributive property looks like.
a(b+c)=a*b+a*c but we are going to rewrite a*b and a*c as 5*5 and 12* 5
a(b+c)=5*5+12*5
So i'd say its 5*5+5*12 i hope this helps
