2 :3 :4 gives 9 shares (2 + 3 + 4)
9 shares = 120cm
1 share = 120/9 cm = 13 1/3 cm ( or 13.333)
2 shares = 26 2/3 cm
3 shares = 40 cm
4 shares = 53 1/3 cm
Answer:
Yes.
Step-by-step explanation:
You can find it out by factoring but ill do it easier way.
(x + 1 ) = 0 put the first and second equation to 0
x = -1
x³ + 2x² - 5x - 6 = 0 Now plug in the x in the equation
(-1)³ + 2(-1)² - 5(-1) - 6 = 0
0 = 0
so (x + 1) is a factor.

Answer:
x=10 and x=-9
Step-by-step explanation:
Factor:
(x-10)(x+9)=0
x-10=0
x=10
and
x+9=0
x=-9
Answer:
(f+g)(1)
equals
3
Step-by-step explanation:
(f+g)(1) is f(1)+g(1).
f(1) means what y corresponds to x=1 so f(1)=-1.
g(1) means what y corresponds to x=1 so g(1)=4.
So (f+g)(1)=f(1)+g(1)=-1+4=3.
