Please help! I’m very confused on this question. I’m not very good at geometry.
Ahat [919]

Well, to find the perimeter we have to add all of the side lengths, so let's do that:

2x+3 +2x+3 +2x

And we know that this equals 36 so let's solve for x

2x+3+2x+3+2x = 36

6x+6 = 36

6x = 30

x = 5

So we know know that x = 5.

Now all you have to do is plug in the values of x into the lengths

2(5) + 3

= 10+3

= 13 is the length of two of the sides.

2x

= 2(5)

= 10

And 10 is the length of the last side.

Express the recurring decimal 0.034 as a fraction in its simplest form.
LiRa [457]

Answer:

\frac{17}{495} will be the fraction.

Step-by-step explanation:

Here the recurring decimal number is 0.0343434....

To convert this recurring decimal to fraction we assume,

x = 0.03434....   -------(1)

Now multiply both the sides with 100.

100x = 3.43434.... ------(2)

Now subtract equation (1) from equation (2).

100x = 3.43434

<u>      x = 0.03434</u>

99x = 3.4

x = \frac{3.4}{99}

  = \frac{34}{990}

x = \frac{17}{495}

Therefore, fraction that represents the decimal number is \frac{17}{495}
