X^2 -5x -20=0
(x - 5/2)^2 -20 -25/4=0
(x-5/2)^2-105/4=0
(x -5/2 -(105)^1/2)(x -5/2 +(105)^1/2)=0
factors are (x -5/2 -(105)^1/2) and
(x -5/2 -(105)^1/2)
Answer:
The Farmer's Almanac
Step-by-step explanation:
The frequency of chirping varies according to temperature. To get a rough estimate of the temperature in degrees fahrenheit, count the number of chirps in 15 seconds and then add 37. The number you get will be an approximation of the outside temperature.
Hope this helps
Answer:

Step-by-step explanation:
By properties of parallelograms we know that opposite are the same so we have

so for the angles we have

1)5^2
2)8^5
3)9^3
4)2^4
5)7^6
6)2.3^2
