Answer:

2(y^2+17)

Step-by-step explanation:

First, add 13 and 21 together.

You'll end up with 2y^2+34

Then, factor out the two from each term, to get 2(y^2+17).

Since you can factor nothing else out, that will be your answer.

In a football tournament, each team played exactly 19 games. Teams get three points for everyone and one point for every time. A

We can actually deduce here that when the tournament ended, team Olympus have tied for 13, 10, 7, 4, 1 times.

<h3>What is inequality?</h3>

In Mathematics, inequality is used to express or show quantities that are less than, greater than, greater than or equal to,  less than or equal to.

The following can be seen in inequality expressions:

  • ≤
  • ≥
  • >
  • <
  • ≠

Looking at the question, we can see that each team plays exactly 19 games.

Every win (w) = 3

Every tie (t)= 1

Every loose = 0

But Olympus got a total of 28 points

Thus: 3w + t = 28 ---------(1)

Note that each team plays  19 games

Thus, T + W  ≤  19 --------------(2)

and T , W ≥ 0

Looking at equation (1) and (2)

=> 2W  ≥  9

=> W ≥ 4.5  

( match can be won in integers only )

=> W  ≥  5  

W - 5, 6, 7, 8, 9    

T - 13, 10, 7, 4, 1  

Loose - 1, 3, 5, 7, 9

Thus, team Olympus have tied for 13, 10, 7, 4, 1 times.

*PLSSSSS HELP*
klemol [59]

Answer: 39 untits 2

Step-by-step explanation:

Hi, to answer this question, first we have to calculate the perimeter (sum of sides) of the triangle:

Perimeter: 7+6+9.22 = 22.22 units

Then we have to apply the circumference (C) formula:

C = π x diameter

Since C = perimeter of the triangle:

22.22 = 3.14 d

22.22 /3.14 =d

7.08 = d

Finally, we apply the next formula:

Area of a circle = π (d/2)^2

Replacing:

A = 3.14 (7.08/2)^2 = 39.30 units2 = 39 units 2
