Answer:
20 cm
Step-by-step explanation:
First, find the length of one side of the square. Here A = 25 cm^2 = s^2, where s represents that length. Thus, s = 5 cm.
Next, find the perimeter of the square. P = 2(length) + 2(width). For a square, where length=width, P = 4s.
In this problem, P = 4(5 cm) = 20 cm

Step-by-step explanation:
I decided to eyeball it and divide 17.5 by 20 and i got 87.5 :)
Ok so 7:12 is already in it's simplest form because there is nothing that can go into both 12 and 7 (which is a prime number). So in fraction form it would be 7/12
<span>8:10, so a number than can go into both 8 and 10? 2 can go into 8 4 times, and 10 5 times. So the fraction would be 4/5 which is in simplest form (5 is prime) </span>
<span>25:50, again, what can go into both 25 and 50? 5 can. 5x5= 25 5x10=50. The fraction would be 5/10, which can be reduced to 1/2. </span>
<span>80:60, 10 can go into both of them. 8/6 which can be reduced to 4/3 (2 goes into 8 4 times and 2 goes into 6 3 times) </span>
<span>78:780, 2 can go into 78 32 times and can go into 780 390 times. 32/390 can be reduced to 16/195, which I believe is in it's simplest form (no number can go into both 16 or 195 evenly). </span>
<span>All the other ratios are solved similarly, so I think you can do it. </span>
<span>XD hopefully I explained it correctly, but you should also ask an adult to help you and/or correct your homework when you're done.</span>
F(x) = 2 is a linear function that is parallel to the x axis at y=2
It neither increase nor decrease. It's just parallel to x'ox
Since two of the quantities are squares and the sum of all of three is equal 21, then the possible values of those two quantities are: 1,4,9,16
Let's consider each possibility
1 and 4
21-1-4=16, but 16 is also square and there can be only two square so NO
1 and 9
21-1-9=11, but 11 is prime, so NO
1 and 16
21-1-16=4... 4 is a square ,so NO
4 and 9
21-4-9=8 , 8 is not prime and not a square, so YES
4 and 16
21-4-16=1, but 1 is a square ,so NO
9 and 16
9+16=25>21 so.. NO
<u>Therefore, the amounts in the first three bowls are 4,8,9.</u>
