Answer:
Step-by-step explanation:
1. 27.7n + 5.5 = 144.25
2. 27.7n = 138.75
3. n = 138.75/27.7
4. n = <em>about</em> 5.00903 or 2775/554
So the coefficient are the numbers when you multiply a number by a varriable
for example the first part of this equation starts with 3x
3 is the number and x is the viable
that means that the first coefficient in this problem is 3
so moving forward the second coeffifient would be 7 since 7y comes after the first coefficient
yes you are right, density formula is :
density = mass ÷ vol
Your answer would be 200^2in. 8*10 = 80. 80*2(because the box has an opposite side)= 160. Then 2*10 = 20. 20*2 (for the same reason)= 40. 160 + 40 = 200.
You can distribute the q to both terms to get
