45 divided by 8 is 5 r. 5. You can write this like 5 5/8 too.
81p²+90p+25=(9p)²+2*9p*5+5²=(9p+5)²
so the side length of the paining is 9p+5
Answer:
an = 1/2 (n) (n+1)
Step-by-step explanation:
1,3,6,10,.........
3-1=2
6-3=3
Each term is different so there is no common difference. It is not an arithmetic sequence
3/1=3
6/3 =2
Each term is different so there is no common ratio. It is not a geometric sequence
1 3 6 10
+2 +3 +4
a1 = 1
a2 = 3
a3 = 6 = 2*3
a4 = 10 = 2*5
Data:
x y
16 4
32 16
48 36
Direct relation means that the ratio y / x is constant.
So, let's examine this ratio:
Ratio y / x
4/16 = 1/4
16/32 = 1/2
36/48 = 3/ 4
Given that the ratio y/x is not constant, the conclusion is that y does not vary directly with x.
