Answer: 
Step-by-step explanation:
You have the following information given in the problem:
- The number of soccer fans that are going to a soccer game is 27.
- A ticket to the game costs $18 per person.
- The cost of the lunch for all 27 fans is $172.
- 
represents the total cost of attending the game for all 27 fans.
Therefore, keeping the above on mind you can write the following expression that closely estimates the total cost of attending the game for all 27 fans:
Answer:
10:00
Step-by-step explanation:
Jayana is trying to run 30 miles by the end of the months.
30% / 100% = 9 / x
9 * 100 = 900
900 / 30 = 30 miles
Answer:(x^2+y^2)^2=(x^2+y^2)(x^2+y^2)
Step-by-step explanation:
We can rewrite left side into right side form
(x^2+y^2)^2=(x^2+y^2)(x^2+y^2)
we can expand it
(x^2+y^2)^2=x^4+x^2y^2+x^2y^2+y^4
(x^2+y^2)^2=x^4+y^4+2x^2y^2
we can add and subtract 2x^2y^2
(x^2+y^2)^2=x^4+y^4+2x^2y^2+2x^2y^2-2x^2y^2
(x^2+y^2)^2=x^4-2x^2y^2+y^4+2x^2y^2+2x^2y^2
(x^2+y^2)^2=x^4-2x^2y^2+y^4+4x^2y^2
(x^2+y^2)^2=x^4-2x^2y^2+y^4+(2xy)^2
(x^2+y^2)^2=(x^2-y^2)^2+(2xy)^2
