Answer:

<h2><em><u>t = 15.2 is the answer</u></em></h2>

Step-by-step explanation:

<h2><em><u>1. Make an equation</u></em></h2>

numbers to find perimeter = perimeter

Side + Side + 2 unknown sides = perimeter

12 + 7.8 + 2t = 50.2

<h2><em><u>2. Simplify like terms</u></em></h2>

19.8 + 2t = 50.2

<h2><em><u>3. Solve</u></em></h2>

19.8 + 2t = 50.2

-19.8 - 19.8

2t = 30.4

<h2><u><em>4. Check:</em></u></h2>

12 + 7.8 + t + t = 50.2

12 + 7.8 + (15.2) + (15.2) = 50.2

<h2><em><u>50.2 = 50.2</u></em> Correct!</h2><h2 />

Hope this helped,

Answer:

t = 15.2 miles

Step-by-step explanation:

First, let's add the top and bottom numbers together.

Next, we subtract that from 50.2 to get the combined value of both t's.

Finally, we can divide 30.4 by 2 to get the value of t.

<em>30.4 ÷ 2 = </em><em>15.2 mi</em>

<em />

To check our answer, we can add all the sides up to see if they equal to 50.2. 15.2 + 15.2 = 30.4

30.4 + 12 + 7.8 = 50.2

A sequence starts 1, 4, 9, 16 ... The nth term is n^2. Use this fact to find the nth term of the following sequences: a) 2, 5, 1

OleMash [197]

Answer:

n²+1

2n²

Step-by-step explanation:

We can see that 2, 5, 10, and 17 becomes 1, 4, 9, and 16 when we subtract 1.

So it adds 1. The nth will be n² + 1.

2, 8, 18, and 32 is the double of n². 1, 4, 9, and 16 are their half.

So the nth term becomes 2n².
