Step-by-step explanation:
The x int- is -6x and the y int- is 36
A=1/2(a+b)h ↔ A= [(a+b).h]/2
Cross multiplication:→2A = (a+b).h.
Divide both sides by (a+b):
2A/(a+b) =h
Answer:
24/49
Step-by-step explanation:
Let's add the terms and see if there's a pattern

Suppose we say the sum of n terms is (n/(2n+1)), the next term in the series will be 1/((2n+1)(2n+3)) and adding that to the presumed sum gives ...

Then it appears the sum of n terms is (n/(2n+1)). So, the sum of 24 terms is ...
