Answer:
108 in²
Step-by-step explanation:
Given that the legs of a right triangle are 12" and 18".
Be cause it is a right triangle (with 90 degrees between the legs), we can arbitrarily assign one of these to be the height and the other value automatically becomes the base.
Let 12" be height and 18" be base
area = 1/2 x height x base
= 1/2 x 12 x 18
= 108 in²
2mn + 5m + 1
Answer: what do you have to do ??
I'm guessing the series is
Use the ratio test: we have
The series converges for
which has a radius of convergence of 1.
