Answer:-2
Step-by-step explanation:
(n + 3) 5 = 3 x 1 - n
distribute so 5n + 15= 3 - n
subtract three from both sides
5n - 12 = -n
subtract 5n from both sides
12 = −6n
Divide both sides by -6
n=-2
Answer:
15 5/8 in³ (=15.625 in³)
Step-by-step explanation:
recall
volume of cube = length ³
given length = 2 1/2 = 5/2 inches
volume of cube,
= (5/2) ³
= 5³ / 2³
= 125 / 8
= 15 5/8 in³
Answer:
x = -5 or x = 5 (-1)^(1/3) or x = -5 (-1)^(2/3)
Step-by-step explanation:
Solve for x:
x^3 = -125
Taking cube roots gives 5 (-1)^(1/3) times the third roots of unity:
Answer: x = -5 or x = 5 (-1)^(1/3) or x = -5 (-1)^(2/3)
Answer:
x (4x to the second power - 7)
