Select the correct answer. Select the function that defines the given sequence.
–8, -20, -50, –125, 825, ...

A. f(n) = -8•(2/5)^(n-1)
B. f(1) = 8
f(n) = -2/5•f(n-1), for n = 2,3,4…
C. f(1)= -8
f(n) = 5/2•f(n-1), for n = 2,3,4…
D. f(n) = -8•(-5/2)^(n-1)

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
