Answer:
9) x = 4 D)
10) x = 7 B)
Step-by-step explanation:
9)
Vertical angles are congruent.
23x - 2 = 90
23x = 92
x = 4
10)
Vertical angles are congruent.
18x - 6 = 1 + 17x
x = 7
Answer:
3f - 2f = 6 + 23( collection of like terms)
f = 29
Answer:
-10
Step-by-step explanation:
f(n)= f(n-2)+f(n-1)
• Put n = 3
=> f(3) = f(3-2) + f(3-2)
=> f(3) = f(1) + f(2)
=> f(3) = -6 + -4
=> f(3) = -10
I believe that the answer is 10 times bigger
