Answer:
Step-by-step explanation:
16p² = 29
p² = 29/16
p = ±√(29/16)
x² = -18
x = ±√(-18)
x = ± √9•√2•√-1
x = ± 3√2i
5(x - 1)² + 42 = 447
5(x² - 2x + 1) + 42 = 447
5x² - 10x + 5 + 42 = 447
5x² - 10x - 400 = 0
x² - 2x - 80 = 0
x = (2 ±√(2² - 4(1)(-80))) / (2(1))
x = (2 ±√324) / 2
x = (2 ±18) / 2
x = 1 ± 9
x = -8 , 10
3(x - 9)² = -100
3(x² - 18x + 81) = -100
3x² - 54x + 243 = -100
3x² - 54x + 343 = 0
x = (54 ±√(54² - 4(3)(343))) / (2(3))
x = (54 ±√-1200) / 6
x = (54 ± (20√3)i) / 6
x = 9 ± ⅓(10√3)i

25 letters for second spot
9 numbers
6561 times 625
=4,100,625
answer:
Subtract 12 from both sides
explanation:
you need to subtract 12 from both sides to get x by itself
one inch is 500 miles
therefore, every inch on the map is 500 miles.
8 inches would be 8*500
8*500=4000.
4000 miles is your answer.
