I think you meant to say the ratio of the areas (not perimeters). Also, HKO and FGO are not showing up, so it seems like a different problem. I'm going to answer the question you posted in the image attachments.
The triangle ABC has area 12 since
A = b*h/2 = 4*6/2 = 24/2 = 12
Triangle CEF has area 48 because
A = b*h/2 = 8*12/2 = 96/2 = 48
The ratio of the areas is found by dividing the area of ABC over the area of CEF (as the last box instructs) so we have 12/48 = 1/4
Therefore, the area of ABC is 1/4 that of the area of CEF
----------------------
In summary,
<h3>Answer for the first box: 12</h3><h3>Answer for the second box: 48</h3><h3>Answer for the third box: 1/4</h3>
The answer is A (3). In the question you are given a list of numbers, these are the results from the science project. In the list, the number 12 appears 5 times, therefore 5 dots are added above the number 12 on the dot plot. 11 appears once, 13 appears 3 times, 14 appears 3 times and 15 appears three times. Hope this helps.
(-1,1) (6,9)
distance = root (x1-x2)²+(y1-y2)²
so root (-1-6)²+(1-9)²= root 113 or 10.6 ≈11
the answer is B. 11.18 units
<span>-1<0
so use 2x+1
2(-1)+1=-2+1=-1

Since -1 is less than 0, this means that F(x) = 2x+1. This is because F(x) = 2x+1 when x < 0</span>
