Let these there numbers be assigned to variables x, y and z. Since you want to find the sum, add all numbers. However, the sum has boundaries between 10 and 20. Therefore, you will have to use inequality symbols. The two addition equations that could be formulated are:
<em>x+y+z > 10</em>
<em>x+y+z < 20</em>
Answer:
400 times larger
Step-by-step explanation:
Divide as follows:
4*10^6
------------ = 4*10^2 or just 400

I believe this is the answer. Please let me know if it's correct.
39.4 is ur answer because 3.14 x 2 (the radius) is 6.28 and if you square it you get 39.4
Answer:
6x^2 + 8x + 28
Step-by-step explanation:
2 times the length plus 2 times the width gives the perimeter
2(3x^2 + 3x + 6) + 2(x + 8)
6x^2 + 6x + 12 + 2x + 16
6x^2 + 8x + 28
