Answer:
Second term=9
Third term=14
Twelfth term=59
Eightieth term=399
nth term=-1+5n
Step-by-step explanation:
First term=a=4
Common difference=d=5
using the formula
Tn=a + d x (n-1)
Second term=4 + 5 x (2-1)
Second term=4 + 5 x 1
Second term=4 + 5
Second term=9
3rd term=4+5x(3-1)
3rd term=4+5x2
3rd term=4+10
3rd term=14
12th term=4+5x(12-1)
12th term=4+5x11
12th term=4+55
12th term=59
80th term=4+5x(80-1)
80th term=4+5x79
80th term=4+395
80th term=399
nth term=4+5(n-1)
nth term=4+5n-5
nth term=4-5+5n
nth term=-1+5n
I am not really sure but x=1.84 and y=-1.064

Answer:

Step-by-step explanation:
we know that
The <u><em>Trapezoid Mid-segment Theorem</em></u> states that: A line connecting the midpoints of the two legs of a trapezoid is parallel to the bases, and its length is equal to half the sum of lengths of the bases
so In this problem
![EF=\frac{1}{2}[AD+BC]](https://tex.z-dn.net/?f=EF%3D%5Cfrac%7B1%7D%7B2%7D%5BAD%2BBC%5D)
substitute the given values
![x=\frac{1}{2}[(x-6)+(2x-3)]](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1%7D%7B2%7D%5B%28x-6%29%2B%282x-3%29%5D)
![x=\frac{1}{2}[3x-9]](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1%7D%7B2%7D%5B3x-9%5D)

so
