What is the gcf of 18 and 36 and 54

18 is the GCF

Step-by-step explanation:

The factors of 36 are:

1, 2, 3, 4, 6, 9, 12, 18, and 36

The factors of 54 are:

1, 2, 3, 6, 9, 18, 27, and 54

The factors of 18 are:

1, 2, 3, 6, 9, and 18

All of the numbers have 18 as the greatest common factor.

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.

the radius is 2 times the diameter.
