For two lines to be perpendicular, their slopes must be negative reciprocals of one another, mathematically:
m1*m2=-1, in this case our reference line has a slope of -3 so:
-3m=-1 divide both sides by -3
m=-1/-3
m=1/3
So the perpendicular line will have a slope of 1/3
First do 8 + 4 which is 12
Next do 12 times 2 which is 24
Final step is to do 24 divided by 1 which gets you 24
The answer is 24.
Answer:
116*
Step-by-step explanation:
36* + 28* = 64*
180* - 64* = 116*
You have to subtract the 6 first and then divide the rest by 1/8.
34-6=28
28×1/8=224
The third one its already in order
