Answer:
in order from images displayed, x = 20, x = 6, x = 5.5
Step-by-step explanation:
4x - 8 + 6x - 12 = 180
10x -20 = 180
10x = 200
x = 20
5x - 1 = 29
5x = 30
x = 6
14x - 6 = 12x + 5
2x = 11
x = 5.5
Answer:
Step-by-step explanation:
∑⁴ₙ₌₁ -144 (½)ⁿ⁻¹
This is a finite geometric series with n = 4, a₁ = -144, and r = ½.
S = a₁ (1 − rⁿ) / (1 − r)
S = -144 (1 − (½)⁴) / (1 − ½)
S = -270
If you wanted to find the infinite sum (n = ∞):
S = a₁ / (1 − r)
S = -144 / (1 − ½)
S = -288

Answer: it’s A
Step-by-step explanation: Because you add three each time, so starting from -4 you go to -1 and then 2 and then 5 and then the fourth number 8
The area of an equilateral triangle of side length "s" is
.. A = (√3)/4*s^2
Your triangle will have an area of
.. A = (√3)/4*6^2 = 9√3 . . . . . square units
