Answer:
550 feet below see level
Step-by-step explanation:
800-250=550
Answer:
(2x+5)(x+4)
Step-by-step explanation:
2x²+13x+20
_5_+_8_=13
_5_×_8_=(2x20)
now it can be re-written as
2x²+5x+8x+20
which can be factored to be:
(2x+5)(x+4)
There are 6! possible permutations of the blue books, 2 possible permutations of the red books, 4! possible permutations of the green books and 3! possible permutations of the three color groups. therefore the total number of ways of arranging the books is given by:
cos (θ) = adj/hyp
cos (70) = 25/x
x cos (70) = 25
x = 25/cos(70)
x = 73.10 m (nearest hundredth)
Answer: 73.10 m
