Answer:
d=12
Step-by-step explanation:
The first term of an arithmetic sequence is i.e. a = 5
We are given that eleventh term is 125
Formula of nth term =
Where a is the first term
n is the term no.
d is the common difference
Substitute n = 11
Hence The common difference of the arithmetic sequence is 12
Answer:40%
X= 17.5
the outside of the triangle always = 180
so you need to add up all the sides and equal to 180
5x+35+x+5+2x=180
add like terms
8x+40=180
get the x alone
x=17.5
y=7
The slope is (7-7)/(3+7) = 0. So, the line is a horizontal line.
The y value of both points is 7.
