1400 grams in kilograms = 1.4
1400 grams in pounds = 3.086472
Answer:
N(11 , 13)
Step-by-step explanation:
M(3,4) = (x,y)
A(-5, -5) = (x1,y1)
N ( )=(x2,y2)
using midpoint formula;
M(x,y)=(x1 + x2)/2 , (y1 + y2)/2
(3,4)= (-5 + x2)/2 , (-5 + y2)/2
Now;
3 = (-5+x2)/2 4 = (-5 +y2)/2
6 = -5 +x2 8 = -5 +y2
6+5 = x2 8+5=y2
x2=11 y2 = 13
1. The terms of a sequence are denoted by

2.

3. so it is clear that the first columns add each time by one, and the second column add by 2, then by 4, by 6, by 8 and so on.
4. consider only the second column and how we get the terms, which we will call

:


5.
So
![u_{n}=(n+1)(1+2{1+2+3+....(n-1)}) =(n+1)(1+2 [(n-1)n/2]) = (n+1)(1+(n-1)n) =(n+1)( n^{2}-n+1 ) ](https://tex.z-dn.net/?f=u_%7Bn%7D%3D%28n%2B1%29%281%2B2%7B1%2B2%2B3%2B....%28n-1%29%7D%29%0A%20%20%20%20%20%20%20%20%0A%20%20%20%20%20%20%20%20%20%3D%28n%2B1%29%281%2B2%20%5B%28n-1%29n%2F2%5D%29%0A%0A%20%20%20%20%20%20%20%20%20%3D%20%28n%2B1%29%281%2B%28n-1%29n%29%0A%20%20%20%20%20%20%20%0A%20%20%20%20%20%20%20%20%20%3D%28n%2B1%29%28%20n%5E%7B2%7D-n%2B1%20%29%0A%20%20%20%20%20%20%20%20%20)
6. We can check:

7. Remark: Gauss addition formula: 1+2+3+....+n=n(n+1)/2
Parallelograms, have 2 pairs of parallel lines. The diagnosis are congruent, so one diagnosis makes 2 congruent triangles. Use the WSS triangle theorem. We have congruent angles.
Answer:
The correct option is B.
Step-by-step explanation:
Elijah drew a triangle that has one side longer than the other two.
Now, we know that the length of a side of a triangle is always less than the total length of the other two sides of the triangle.
Therefore, the correct option that we have to choose will be B.
That gives, 'the sum of the two shorter side lengths must be greater than the length of the longest side'.
