Answer:
x^4 - 8 x^2 + 16
Step-by-step explanation:
Use formula (a-b)^2 = a^2-2ab+b^2
now a=4 b=x^2, plug in
Minutes. Because you cannot concert minutes to hours.
1 hour= 60 Minutes
2 hours= 120 Minutes

2 + -9n = 56. -9n = 54. N = -6
Step-by-step explanation:
u vector components:
x-comp = 8 - (-17) = 25
x-comp = -11 - 4 = -15
Therefore, we can write vector u as
u = 25i - 15j
v = 14i - 4j
u - v = 11i - 11j
Therefore,
2(u - v) = 22i - 22j
