Answer:
4565
Step-by-step explanation:
The area of a triangle is

(4.5feet)(5.75feet) and that would equal 12.9375 feet²
The answer to the question is a direct variation. k=2
The answer is c
25/5 is 5
So 5>4
Answer:
3
Step-by-step explanation:

And,
$ \sum (2i+1)= \sum (2i)+ \sum_{i=1} ^{4} (1) $
$=\sum_{i=1} ^{4}(2i) + 1+1+1+1 $
$=\boxed{\Big(\sum_{n=1} ^{4}(2n)\Big) +4}.... \text{Variable in Summation doesn't matter}$
Hence the difference is 3.
