Answer:
(3x^2 - 2x + 5)
Step-by-step explanation:
3x^2 - 2x + 5
- <u>(6x^3 + 3x^2)</u>
-4x^2 +8x +5
- <u>(-4x^2 - 2x)</u>
10x + 5
-(<u>10x + 5)</u>
00
(2x+1) (3x^2 - 2x + 5) = 6x^3 - x^2 + 8x + 5
Therefore the other factor of the polynomial is (3x^2 - 2x + 5)
Answer:
104 degrees
Step-by-step explanation:
90 + 54 + 132 = 276
360 - 276 = 104
There could be one more pentagon
**As far as I know
Answer:
She went on the slide 8 times and on the roller coaster 4 times
Step-by-step explanation:
We convert each statements to a mathematical equation.
Firstly, let's represent the number of times she went on the coaster with R and the number of times on the slide with S. We know quite well she went on 12 rides. Hence the summation of both number of times yield 12.
Mathematically, R + S = 12. ........(i)
Now we also know her total wait time was 3hours. Since an hour equals 60 minutes, her total wait time would equal 180 minutes.
To get a mathematical representation for the wait time, we multiply the number of roller coaster rides by 25 and that of the slides by 10.
Mathematically, 25R + 10S = 180 .......(ii)
Here we now have two equations that we can solve simultaneously.
From equation 1 we can say R = 12 - S. We can then substitute this into equation 2 to yield the following:
25(12 - s) + 10s = 180
300 - 25s + 10s = 180
300 - 25s + 10s = 180
300 - 15s = 180
15s = 300 - 180
15s = 120
S = 120/15
S = 8
S = 8 , and R = 12 - S = 12 - 8 = 4
