(4x-5)^2 = 49

Extract square root from both sides

4x-5 =(+/-)7

4x = 5 +7 and 4x = 5 -7

4x = 12 and 4x = -2

x = 12/4 and x = -2/4

x= 3 and x =-1/2

Find the greatest common factor of 36 and 54
8090 [49]

Hey there!

To find the greatest common factor you will need to find all the factors of 36 and 54. (A factor is a number that can be divided into another number).

54 - 1, 2, 3, 6, 9, 18, 27.

36 - 1, 2, 3, 4, 6, 9, 12, 18.

As you can see here, the factor that is the greatest is 18. Therefore, that is your answer.

Hope this helps! :)
