One way to I solve this is by listing all the ways it can be multiplied by:
72: 1*72, 2*36, 3*24, 4*18, 6*12, 8*9.
80: 1*80, 2*40, 4*20, 5*16, 8*10.
Group the factors that they have in common.
Which are 1, 2, 4, and 8.
After that, find the greatest common factor that they both share.
Answer: 8
Answer:
They are perpendicular to each other
Step-by-step explanation:
Answer:
x = 1.5
Step-by-step explanation:
2x^2 = 3x
divide whole eqn by x
2x = 3
x= 3/2 =1.5
Answer:
No.
Step-by-step explanation:
Of course not. Place a hardback book standing up on your desktop and open the two hard covers to some arbitrary angle. The planes of the covers are each perpendicular to the desk top, but not parallel to each other (or necessarily perpendicular to each other).
