3x²-8x+4=0
(3x-2) (x-2)=0
x=2/3 , x = 2
Hence, the polynomial has two positive roots.
Option A is the correct choice.
Answer:
+ 5°
Step-by-step explanation:
Given,
Good morning temperature = -15°
Raise in temperature = 20°

Answer:
(x+y+z)=79
5x+2y+z=859
2x+3y+9z=498
Step-by-step explanation:
Its writing 3 different equations that have the same value for the same variable.
So whole ml's
30 mls
find what 30 is evenly divisble by
factor 30
30=2 times 3 times 5
therefor
30 is divisble by 2,3,5,6,10,15
so he can divide the glass into 2 sevings which is 30/2=15 ml in each
servings ml fraction
2 15 15/30=1/2
3 10 10/30=1/3
5 6 6/30=1/5
6 5 5/30=1/6
10 3 3/30=1/10
15 2 2/30=1/15
