Let the second side be x

then,
first side = twice the length of the second side
= 2x

third side = 20 feet less than three times the second side
3 (second side ) - 20
= 3 (2x) -20
= 6x - 20

perimete of a triangle = sum of all sides,

substitute the values we know,
and you'll be left with this equation

106 = x + 2x + 6x - 20
106+ 20 = 9x
126 = 9x
126/9 = x
14 = x

so,

measure of second side = x = 14 feet

measure of first side = 2x = 2 (14) = 28 feet

measure of thurd side = 6x - 20 = 6 (14)-20 = 84- 20 = 64 feet.

Answer:

Step-by-step explanation:

Hello, please consider the following.

For any x real number different from 0, we can write.

\dfrac{2y + x}{x} = 2y\\\\2y+x=2xy\\\\2xy-x=(2y-1)x=2y\\\\x=\dfrac{2y}{2y-1}

And this is defined for 2y-1 different from 0, meaning y different from 1/2

Thank you.

what property could you used to show that the distance between the elephants and giraffes is the same as the distance between th
Nadya [2.5K]

There are several algebraic properties of equality.

<em>The property that shows that both distance are the equal is the symmetric property of equality</em>

Represent the distance between the elephants and the giraffes with x

Represent the distance between the tigers and the zebras with y

The symmetric property of equality states that:

<em>For 2 expressions or numbers; x and y</em>

<em>If x = y, then y = x</em>

<em />

<em />

<em />

In this context, the above property means that:

<em>If the distance between the elephants and the giraffes is the same as the distance between the tigers and the zebras, then both distance are equal</em>

<em />

Hence, the property to use is the symmetric property of equality
