Here you should add the like terms; so 6 + 3 = 9 and 5*(sq.root of 5) - 2*(sq.root of 5) = 3*(sq.root of 5), therefor the answer would be 3*(sq.root of 5) + 9
Remember that surds can be added or subtracted if the term underneath the square root sign is the same :)
<u>136 + x + x = 180. Or, to simplify, 136 + 2x = 180. The congruent angles measure 23 degrees each.</u>
We know this because of a simple rule that goes for all triangles: The measures of all three angles in a triangle will <em>always</em> add up to 180 degrees.
One angle of a triangle measures 136 degrees. The other two angles are congruent (have the same measure).
(x stands for an unknown angle measure.) So the equation we would use is 136 + 2x = 180. We can solve this within a few steps.
1. We subtract 136 from 2x in order to isolate 2x. But if we subtract something from the left side of the equation, we have to subtract it from the right side too. Otherwise the equation will be wrong; We would be taking away the balance.
2x = 180 - 136
2. Now that 2x is isolated, we solve 180 - 136.
2x = 46
3. If we know now that 2x is equal to 46, how do we find out what x is equal to? We divide by 2 (on both sides or it'll be wrong) to get x.
2x = 46
2x/2 = 46/2
x = 23
Now we know! x = 23... The other two angles are both 23 degrees. We can check to see if that's right by solving 23 + 23 + 136... Does it add up to 180? Yes! :)

Answer:
blue
Step-by-step explanation:
it is going along with the points. we know it cant be red because that line is negative and the dots are going in a positive direction. we know it cant be pink bc it's not even going in the same direction as the points. so it has to be blue
