Answer:
All statements are true
Step-by-step explanation:
1. The statement 
is true, because 
is the sum of first 499 terms, 
is the sum of first 500 terms, and all these terms are positive, then the sum of smaller number of terms is less than the sum of larger number of terms.
2. The statement 
is true, because is the sum of first 500 terms, 
is 500th term and the sum of 500 terms is greater than the 500th term.
3. The statement 
is true, because 
is the sum of first 1 term that is exactly 
All statements are true.
Answer:
They are (6, 1) or (3, 2).
Step-by-step explanation:
The factor pairs of 6 are 1×6 and 2×3
So the parallelogram (height by length) could be:
1 by 6
2 by 3
3 by 2
6 by 1.
Answer:
ΔABC≅ΔDEC by AAS
Step-by-step explanation:
You can use the AAS method of congruency.
Since you already have <BAC and <EDC congruent to eachother, and sides BC and EC congruent to each other, you only need that one remaining angle in between. <ACB can be proven congruent to <DCE by the Vertical Angles Theorem, and that gives you the AAS you need to prove that these two triangles are congruent
Hope this helped.
