2(3x) and 2(-9)
so 2*3x equals 6x and 2*-9 equals -18
6x-18

Perimeter of a square whose area is 25cm^2
Aleonysh [2.5K]

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

What's the ratio in simplest form 20 and 60
Natalija [7]
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>

A table has five bowls. None of the quantities in the bowls are prime, though the last two bowls are empty. Two of the quantitie
Digiron [165]

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>
