A = first piece, b = second piece, c = third piece
a + b + c = 47
b = 3a
c = 5a + 2
a + (3a) + (5a + 2) = 47.....combine like terms
9a + 2 = 47
9a = 47 - 2
9a = 45
a = 45/9
a = 5 ft
b = 3a.....b = 3(5)....b = 15 ft
c = 5a + 2....c = 5(5) + 2.....c = 25 + 2....c = 27 ft
longest piece (c) = 27 ft
Here are the log properties you need:
Answer:
C) x < 6
Open circle is no line under, closed circle has a line under.
The arrow also goes left so x must be less than 6
Answer:
(x-3)(x-5)
Step-by-step explanation:
X^2-8x+15
Break the expression into groups
(x^2-3x)+(-5x+15)
Factor out x from x^2-3x
Factor out -5 from -5x+15: -5(x-3)
=x(x-3)-5(x-3)
Factor out common term x-3
=(x-3)(x-5)
Thanks for letting me help!!
