Answer: how'd you do that
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
∵a+1,2a+1,4a-1 are in A.P.
2(2a+1)=a+1+4a-1
4a+2=5a
5a-4a=2
a=2
20 times 10 is 200 divided by 2 is 100. so 100 cm squared
Your answer is A) 34.
A rectangle has four sides as you know.
If you use 34 as your width, both sides for width would total 68.
Then, same steps as before, accounting for both length sides by multiplying 68 by 2 and get you’d get 136.
68 (both width sides) + 136 (both length sides) would get your total of 204.
Answer:
Step-by-step explanation:
The standard form of a circle is
where x and y are points on the circle, h and k are the center, and r is the radius. We have what we need to fill in everything but the radius, but we will solve for that like this:
Simplifying gives you
and
so
That means the equation for this circle is
