A circle has a diameter of 9cm
Katen [24]

For the square to fit inside the circle without touching it, the diagonal of the square needs to be less than the diameter of the circle.

Using the Pythagorean theorem we can calculate the diagonal of the square:

X = SQRT(5^2 + 5^2)

X = SQRT(25 + 25)

X = SQRT(50)

X = 7.07

The diagonal of the square is 7.07 cm, which is less than the diameter of the circle, 9cm, so it will fit .

What is -5g + ( -17fg ) =
Anika [276]

Hello from MrBillDoesMath!

Answer:

-g (5 + 17f)    



Discussion:

The terms only have the factor "g" in common so


-5g + ( -17fg) =                       => factor "g" from each term

g ( -5 - 17f) =

-g (5 + 17f)    

is as much as it can be factored.


Thank you,

MrB
