I assume the way it's written is like this
4x^2 - 8x + 4 - (2x^2 - 3x + 7)
If that's the case, just combine like terms.
Let's begin with 4x^2. It has the same components as the -2x^2 (remember, since it's being subtracted in the original equation, the number is negative.)
4x^2 - 2x^2 = 2x^2
Now -8x and 3x (be careful, sometimes there's a minus sign in and out of the parentheses, this makes the number positive again
-8x + 3x = -5x
And then 4 and -7
4 - 7 = -3
So the simplified version is finally:
2x^2 - 5x - 3
Hope this helped! If you need me to explain anything, don't be afraid to ask.
Answer:
It is A. I took the test,
Step-by-step explanation:
its 66 and then the little 3
The expression which is:
3.28 + 3.28 + 3.28 = 9.84
Is simply equivalent to the expression of thrice the value
of 3.28 is equal to 9.84 or:
3 x 3.28 = 9.84
<span>The two are simply equal since in the 1st
expression there are three 3.28 and in the 2nd expression there are
also three 3.28.</span>
Answer:
17
Step-by-step explanation:
Use the Pythogream theorm where c is the hypotenuse.
The total combinations of 5 numbers that can be made from
59 numbers is:
59C5 = 5,006,386
So the probability of winning is:
P = 1 / 5,006,386
P = 1.997 x 10^-7
So the expected payoff is:
P = $1,000,000 (1.997 x 10^-7) - $1 (1 - 1.997 x 10^-7)
<span>P = - $0.80 (loss)</span>
