Answer:
x = 40
Step-by-step explanation:
Here's a fun fact, all of those angles actually add up to 360 degrees!
How do we know this? Well if you were to draw a small arc between each of the lines, you would see that the arc would end up making a circle. And remember, circles have 360 degrees!
Now we can do some basic algebra. Add up all the angles and set that equal to 360.
(2x) + (x) + (3x + 20) + (2x+20) = 360.
8x + 40 = 360
8x = 320
x = 40
Hope this helped!
Answer C
When you multiply that together (c), it gives you p^2, -5p, -2p, and 10. Add the -5-2, and it gives you -7, or the original equation.
Answer:
a=1 converges for 0<x<8
Step-by-step explanation:
Given that a geometric series infinite is given in summation form as

Here I term is when n =0
So a= I term = 
r = common ratio = 
This series converges only if


For 0<x<8, we get absolute value of r is less than 1.
Hence series converges for
