Start with the smallest number, 18:

      The factors of 18 are: 1, 2, 3, 6, 9, 18.

So the GCF for all three must be one of those.

Now consider the next smallest number.  Of the factors of 18, only these are also factors of 27:

    1, 3, 9

Now consider the last number, 54.  Of the remaining factors, 9 is the greatest and 9 goes into 54.

The GCF is 9.

By starting with the smallest number, you usually limit how many factors you'll ever need to consider.

Plz answer all measures plz ASAP thx

Lines <em>a</em> and <em>b</em> are parallel, so lines <em>p</em>, <em>q</em>, and <em>t</em> are considered to be transversals. To solve this, you make use of the fact that alternate interior angles are equal, as are alternate exterior angles, as are corresponding angles. Of course any linear pair of angles is supplementary.

∠1 = 90° — corresponding angle to the right angle above it

∠2 = 68° — the sum of 22° and angles 1 and 2 is 180°

∠3 = 112° — supplementary to angle 2 (and the sum of 22° and 90°, opposite interior angles of the triangle)

∠4 = 112° — equal to angle 3

∠5 = 68° — equal to angle 2; supplementary to angle 4

∠6 = 56° — base angle of isosceles triangle with 68° at the apex; the complement of half that apex angle

∠7 = 124° — supplementary to the other base angle, which is equal to angle 6; also the sum of angles 5 and 6

∠8 = 124° — alternate interior angle with angle 7, hence its equal.

Question 6 (Essay Worth 5 points) Part A: Find a rational number that is between 5.2 and 5.5. Explain why it is rational. (2 poi
insens350 [35]
Rational between 5.2 and 5.5

5.2 × 10/10 = 52/10
5.5 × 10/10 = 55/10
rational no. b/w them is 53/10 = 5.3

rational because it is in p/q form where q is not zero and p and q are integers.



irrational.no. b/w 5.2 and 5.5

Factor 140c + 28 - 14a to identify the equivalent expressions.
Feliz [49]

Answer:

The answer to your question are letters A, C and D.

Step-by-step explanation:

To factor this polynomial we need to look for the common factor of the three terms.

To find it, get the greatest common factor

                        140    28   14     2

                          70    14     7     2

                          35     7     7     5

                            7     7      7     7

                             1     1       1    

Greatest common factor = 2 x 7 = 14  

Factor the polynomial

140c + 28 - 14a = 14 ( 10c + 2 - a)

Factor only 7          7(20c + 4 - 2a)

Factor only 2          2 (70c + 14 - 7a)
