Answer:
x=6
Step-by-step explanation:
24=4x
divide both by 4
equals 6
46 = f/10 - (-43)
46 = f/10 + 43
f/10 = 46 - 43
f/10 = 3
f = 3*10
f = 30
That's 5 lengths for a three sided shape... Are you sure that is the instructions?
I'm new too, but I'm pretty sure if you have a question then you ask it, attach a picture if needed, and people might see it and answer.
Answer:
x = 9 + 6i or x = 9 - 6i
Step-by-step explanation:
x² - 18x + 117 = 0
Complete the square and solve:
(x - 9)² - 81 + 117 = 0
(x - 9)² + 36 = 0
(x - 9)² = -36
x - 9 = ±sqrt(-36)
x - 9 = ±sqrt(-1).sqrt(36)
i = imaginary number = sqrt(-1)
x - 9 = ±6i
x = 9 ± 6i
There are no real solutions, only imaginary ones
9 + 6i and 9 - 6i
