Given the following two statements, what conclusion can be made? Three noncollinear points determine a plane. Points S, O, N are
laila [671]
Actually, this has little to do with mathematics and geometry but has to do more with logical reasoning. You have two clauses to get a conclusion from. The reasoning is as follows:

Clause 1: <span>Three noncollinear points determine a plane
Clause 2: </span><span>Points S, O, N are noncollinear
</span>Conclusion: Therefore, points S, O and N form a plane.

the length of a rectangle is five times its width. if the area of the rectangle is 245 meters squared, find its perimeter
Vikentia [17]

Your answer is 84 meters.


We can call the width x, and thus the length 5x, and then we can say that 5x × x = 245, which simplifies to 5x² = 245, and then we can solve:


5x² = 245

÷ 5

x² = 49

√

x = 7


Now that we know what x is, we can find the perimeter by using it as the width, and then multiplying it by 5 to find its length. This gives us:


(7 × 2) + (5 × 7 × 2) = 14 + (35 × 2) = 14 + 70 = 84


So your answer is 84 meters.


I hope this helps!
