Answer:
x = 0 , 2/3
Step-by-step explanation:
3x^3-x^2=x^2
3x^3-2x^2=0
x^2(3x-2)=0
Now split into two equations:
1)
x^2=0
x=0
2)
3x-2=0
3x=2
x=2/3
Answer:
b=-a
Step-by-step explanation:
we know that b is located the same distance from 0 as another number, a, but in the opposite direction.
so the sum of the two numbers equal zero
a+b=0
a=-b or b=-a
Answer:
2(2 +5)
Step-by-step explanation:
We presume you want to rewrite the expression making use of the distributive property. For that, it is helpful to find a factor common to the two terms. The GCD of 4 and 10 is 2, so we can factor that out:
4 + 10 = 2(2 +5)
_____
Of course, you can use any factor you like. It doesn't need to be an integer.
= (1/3)(12 +30)
= 0.4(10 +25)
= 4(1 +2.5)
Answer:
$26.80
Step-by-step explanation:
(I don't know exactly how other people were taught to do percentages, but this is how I was taught and I find it the easiest for me.)
You are going to subtract your percentage number by 100.
100 - 33 = 67
This will give you your multiplier so you can then get your answer but you have to turn it into a decimal.
0.67 x 40 = 26.80
The answer is b the sun is a rational number
