Answer:
2x+4
Step-by-step explanation:
if you double the triangle, than the sides double as well meaning you use distributive property to multiply two to each integer.
First of all, don't let "b" confuse you. Know that b = 5/6k = -10, so all you really have to solve for this problem is
.
Before anything else, you have to isolate k. Do this my multiplying both sides by the reciprocal of 5/6.

The 6/5 and 5/6 cancel each other out, so we are left with 
--> 
---> 
So k = -12.
Hope this helped. Good luck.
Answer:
probs around 32
Step-by-step explanation:
Divide the circumference by π.
Divide the result by 2 to get the circle's radius.
Multiply the radius by itself to get its square.
Multiply the square by π, or 3.14 for an estimation.
You found the circle's area from the circumference.
