Answer:
=0.5
Step-by-step explanation:
9c + 7 = 4(5c+3)
9c + 7 =20c + 12
-12 + 7 = 20 - 9c
-5 = 11c
-5 divide by 11 = -0.5
First of all you should demand your teachers stop teaching you algebra in geometry class.

Linear pairs (and this is the geometry part) are angles that add to 180 degrees, supplementary angles formed by two lines crossing.
3n + 21 + 2n + 34 = 180
5n + 55 = 180
5n = 125
n = 25
mEFG = 3n + 21 = 96 degrees
mCFH = 2n + 34 = 84 degrees
These are indeed supplements, adding to 180 degrees.

ACD is a right angle because it makes a linear pair along DF with another right angle.
So
mACB + mBCD = 90 degrees
mBCD = 90 - mACB = 90 - 68
mBCD = 22 degrees
<h3>{ 13, 9, 6} represent the sides of a triangle</h3>
<em><u>Solution:</u></em>
<em><u>Use the triangle inequality law</u></em>
The sum of the lengths of any two sides of a triangle must be greater than the third side
<em><u>Option A</u></em>
{13, 9, 6}
Also,
Thus, sum of length of any two sides is greater than third side
Therefore, { 13, 9, 6} represent the sides of a triangle
<em><u>Option B</u></em>
{12, 7, 20}
19 is not greater than 20
Therefore, {12, 7, 20} does not represent the sides of a triangle
<em><u>Option C</u></em>
{25, 50, 75}
75 is equal to 75
Therefore, {25, 50, 75} does not represent the sides of a triangle
