What is the simplest radical form of 45?

Hitman42 [59]

For this question I'm just going to use / as a square root sign because I don't know how to do it on a computer. Anyways...

So you have /45

Now you have to find a factor that is also a perfect square which is 9 (because 9x5=45)

So you now have /9x5

Since 9 is a perfect square (/9=3)

You can re write it is 3/5 which is the answer

Three red rods are 2cm longer than two blue rods. Three blue rods are 2cm longer than four red rods. How long is each rod?

nydimaria [60]

Answer:

The length of each red rod is 10 cm and the length of each blue rod is 14 cm

Step-by-step explanation:

Let

x ----> the length of each red rod in centimeters

y ----> the length of each blue rod in centimeters

we know that

$3x=2y+2$ ----> equation A

$3y=4x+2$ ----> equation B

Solve the system by graphing

Remember that the solution of the system of equations is the intersection point both graphs

using a graphing tool

The solution is the point (10,14)

see the attached figure

therefore

The length of each red rod is 10 cm and the length of each blue rod is 14 cm
