Answer:
D. Lines coincide
Step-by-step explanation:
On dividing y/2y and 4/8 and x/2x you get 1/2. Since 1/2 is common answer for all the parts, lines will coincide.
Step-by-step explanation:
If I'm understanding what a "proof" means, some answers could be:
2 + 3 = 5
4 + 15 = 19
8 + 21 = 29
Hope this helps you! Have a good night!
By figuring out was is X and multiply
Answer: 
Step-by-step explanation:
Let be "C" the circumference of the circle (in feet) and "r" the radius of the circle (in feet).
Based on the information provided in the problem, you know that the circumference of the circle is always
as large as its radius.
Notice that this indicates a multiplication. Then, this means that the circumference of the circle is always equal to
by "r".
Based on this, you can write the following formula that expresses the circumference "C" in terms of the radius "r":
