I would say F cause a triangle sides add up to 180
Answer:
(-1)ⁿ(3)ⁿ/10
Step-by-step explanation:
The first term a = 0.3, the second term, ar = 0.9. The common ratio r = ar/a = 0.9/-0.3 = -3.
From the general term of a geometric series,
U = arⁿ⁻¹
= (0.3)(-3)ⁿ⁻¹
= (3/10)(-3)ⁿ⁻¹
= (-1)ⁿ⁻¹(3)(3)ⁿ⁻¹/10
= (-1)ⁿ(3)ⁿ/10
Answer:
x = -3, y = -7
Step-by-step explanation:
Eliminate the equal sides of each equation and combine.
Solve 2x - 1 = 3x + 2 for x.
-x - 1 = 2
-x = 3
x = -3
Evaluate y when x = -3
y = 3 (-3) + 2
y = -7
(-3, -7)
<em>good luck, i hope this helps :)</em>
Answer:
the answer are B,=6506/82=79.3
C)7031/89=79
the answer are B and C
but maybe option C maybe also right because it is 3193/38=84
