Answer:
3x^2 + 9x + 1
Or
3x ( x + 3 ) + 1
Step-by-step explanation:
(5x - 2 +3x^2 ) + (4x + 3 )
To make this a little bit more easier to read, you can remove the parentheses:
5x - 2 + 3x^2 + 4x + 3
Now, write in a way so that the like terms are next to each other:
3x^2 + 5x + 4x - 2 + 3
Now simplify the 'x' terms to get:
3x^2 + 9x - 2 + 3
Now, simplify the integers (the ones with now variables with them) to get:
3x^2 + 9x + 1
If you want, you can factor out the 3x for two of the terms to get :
3x ( x + 3 ) + 1
Therefore, your simplest form can either be 3x^2 + 9x + 1 OR 3x (x + 3 ) + 1
The probability of obtaining two blue marbles without replacement is equal to 0.15.
We are given that:
The number of yellow marbles = 3
Number of red marbles = 9
Number of Blue marbles = 8
Total marbles = 3 + 9 + 8
Total marbles = 20
Now, we have to calculate the probability of obtaining two blue marbles without replacement.
The probability will be:
P( obtaining two blue marbles without replacement ) = 8 / 20 × 7 / 19
P( obtaining two blue marbles without replacement ) = 56 / 380
P( obtaining two blue marbles without replacement ) = 0.15
Therefore, the probability of obtaining two blue marbles without replacement is equal to 0.15.

Answer:
Return on investment (ROI) = 7%
Step-by-step explanation:
Given:
Amount invested = $10,000
Total amount get (refund) = $10,700
Find:
Return on investment (ROI) = ?
Computation:
Amount Return = Total amount get (refund) - Amount invested
Amount Return = $10,700 - $10,000
Amount Return = $700
![Return\ on\ investment \ (ROI) = [\frac{Amount\ Return}{Amount\ invested} ]100\\\\Return\ on\ investment \ (ROI) = [\frac{700}{10,000} ]100 \\\\ Return\ on\ investment \ (ROI) =7](https://tex.z-dn.net/?f=Return%5C%20on%5C%20investment%20%5C%20%28ROI%29%20%3D%20%5B%5Cfrac%7BAmount%5C%20Return%7D%7BAmount%5C%20invested%7D%20%5D100%5C%5C%5C%5CReturn%5C%20on%5C%20investment%20%5C%20%28ROI%29%20%3D%20%5B%5Cfrac%7B700%7D%7B10%2C000%7D%20%5D100%20%5C%5C%5C%5C%20Return%5C%20on%5C%20investment%20%5C%20%28ROI%29%20%3D7)
Return on investment (ROI) = 7%
Yes, the number of words ARE proportional to the number of minutes she types, away to tell is when it says Bella types at a CONSTANT rate of 42 words per minute. This means for every minute 42 words will be added.
Answer:
x squared plus 2x minus 1.
Step-by-step explanation:
x3+3x2+x-9 is in the division "house" and x-1 is on the outside. xsquare times x equals x cubed. and x square times negative 1 equals -x squsre. put x square on top of the roof. change the signs. the x cubed cancels out. and bring down 2x square from subtracting 3x square and -x square and bring down the x-9. Put 2x on top of the roof too and 2x times x equals 2x square and multiply by -1. U will have 2x square -2x square and -2x plus x which equals -1x cuz the 2x square cancels out. bring down the -9. Now i have -1x-9. Multiply by -1 and put -1 on the roof. -1x+1x cancels out. and -1 times -1 equals positive 1. So -9+1=8. U van do any further cause as soon as the last number is at the end of the roof and u cant go further, ur done dividing. so the answer is x square+2x-1/×-1 +8 as the remainder. hope i helped
