8; 12 greatest common factor what is the answer

4

Step-by-step explanation:

Step 1 : List the prime factors of each number

8 : 2 x 2 x 2

12 : 2 x 2 x 3

Step 2: Identify the numbers that are common between the two sets of prime factors:

in our case, we see that only  "2 x 2" shows up in both lines, hence 2 x 2 is the GCF.

2 x 2 = 4

Hence the GCF is 4

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
