Answer:
A'={a,c,e} by U={a,b,c,d,e,f,g}
A={b,d,f,g}
A' don't double A but answer union a,c,e
Answer:
N= -3
Step-by-step explanation:
4n+2 = 6(1/3n - 2/3)
4n+2 = 2n - 4
2n +2 = -4
2n = -6
n = -3
What we can do is set up an algebraic equation.
our variable can me L for Length
3L+4L+5L=90
now all we have to do is solve
12L=90
---- ----
12 12
L=7.5
now multiple each number in the ratio by 7.5 to find out how long each side is
3 times 7.5 is 22.5
4 times 7.5 is 30
5 times 7.5 is 37.5
the side lengths are 22.5, 30, and 37.5
(1, 64), (2, 32), (4, 16), (8, 8).
