<em>Answer:</em>
A and C
<em>Step-by-step explanation:</em>
We have: <em>C = 5 (2y + 1)</em>
<em> = 5 x 2y + 5 x 1</em>
<em> = 10y + 5 </em>
Besides, <em>A = 10y + 5 </em>too.
SO THE ANSWER IS <em>A and C</em>

Answer:
These two triangles are similar because they have 3 angles in common.
Step-by-step explanation:
We can tell this since they both have right angles in them. We also know that angle X and U are the same since they have the notation. And since all triangles add up to 180, and if the other two angles are the same, then the final angle must be the same too.
Answer:
Step-by-step explanation:
Given that the center of the circle is: (2, -4)
tangent to the line x = -2
The equation of a circle has the following formula:
where a, b is the center and r is the radius
The distance between the circle and the tangent line is:
d = 
= 
d = r so 
= 
= 
the equation of the circle is:
Answer:
Yes
Step-by-step explanation:
If you add two positive numbers, the sum will always be greater.
Ex: 5+5=10
If you add two negatives, the sum will always be greater.
Ex: -5+-5=10
