A=1/2bh
A=1/2* 6.7*8
A=<span>4*6.7
A=</span>26.8 square km
The * represents multiplcation.
The area is 26.8 square kilometers.
You can use this formula of arthenatic series to find sum to get the number of term
sum= n÷2 (2a+(n - 1)d)
n= number of tern = n
a= first term =
d= common difference
sum= 1113
you can find the number of series by putting in them
❤️Hello!❤️ x= 3/49. Hope this helps! ↪️ Autumn ↩️
The degree of the expression is 2.
Answer:
1
Step-by-step explanation:
You "complete the square" by adding the square of half the x-term coefficient. Here, that is ...
((-2)/2)² = 1 . . . . value added to complete the square
If you want to keep 0 on the right, you must also subtract this value:
x² -2x -36 = 0
x² -2x +1 -36 -1 = 0 . . . . . . add and subtract 1 on the left
(x -1)² -37 = 0 . . . . . . . . . . . written as a square
