Here, two side lengths of a triangle given, 18 cm and 40 cm.

We know that, the sum of the lengths of any two sides of a triangle is greater that the third side.

So here, let's take the third side be x.

So we can write ,

18+40 > x

58> x

x

Also we can write,

18+x > 40

We will get x by subtracting 18 to both sides. We will get,

18+x -18 >40-18

x>40-18

x>22

Also we can write,

40+x > 22

As we know 40 >22, so it is obvious 40+x will be greater than 22, as x can not be negative.

So we will take the first two parts, we have got,

x and x>22

By using both of them, we can write,

22

So we have got the required answer. Possible length of the third side is 22.

How to write a fraction or mixed number as a decimal pre algebra?
Oksanka [162]
If you had the number 4 1/4 you would divide the numerator (1) by the denominator (4) and then take the decimal number (0.25) you get and add the decimal to the whole number on your mixed number (4+0.25) and that would give you the decimal.

Find the product of the roots of the equation<br> xl-5x - 36 = 0
Marat540 [252]

Answer:

Step-by-step explanation:

Hello, I assume that you mean

x^2-5x-36

The product is -36.

x_1 \text{ and } x_2 \text{ are the two roots, we can write}\\\\(x-x_1)(x-x_2)=x^2-(x_1+x_2)x+x_1\cdot x_2

So in this example, it means that the sum is 5 and the product is -36.

Thank you
