Answer:
option B
Step-by-step explanation:
9/10 + 6/5 + 3/2...........
We find the difference between the terms


We will get the same difference when we subtract consecutive terms.
so , d= 3/10, a= 9/10
we find the formula for nth term
a_n = a+(n-1) d




we need to find eighth partial sum so we take n=1 to 8
sum of 8 terms (
)
So option B is correct
Answer:
D) x=-1, x=-9
Step-by-step explanation:
x=-1, x=-9
Answer:
B.)21.4
Explanation
A(-4, 3), B(0,2), C(2,4) and D(0,-3)
AB = √(1²+4²) = √17 =4.12
BC = √(2²+2²) = √8 = 2.83
CD = √(2²+7²) = √53 = 7.28
AD = √(4²+6²) = √52 =7.21
Perimeter = 4.12+2.83+7.28+7.21 = 21.44
To the nearest tenth the answer is 21.4.
