step-by-step explanation: h: (- 3, 6)
m: (1, - 2)
o: (7, 6)
r: (- 9, - 2)
midpoint of hm: (- 1, 2)
midpoint of or: (- 1, 2)
therefore, b is the midpoint of both diagonals bisect each other !
to prove the diagonals are perpendicular, show that the product of the slopes = - 1
it's equivalent, so we can say that its equal.
let's call the denominator x and the numerador is 18 less then denominator, x - 18.
multiply
2.x = 5.(x - 18)
2x = 5x - 90
90 = 5x - 2x
90 = 3x
x = 90/3
x = 30
so:
answer: 1722
step-by-step explanation:
given: the mass of saturn=
the mass of mercury=
the number of times the mass of saturn is greater than the mass of mercury
hence, the mass of saturn is 1722 times greater than the mass of mercury.
