The answer in descending powers of x:
Step-by-step explanation:
We have to subtract
from ![4x^2-4x+3](https://tex.z-dn.net/?f=4x%5E2-4x%2B3)
![4x^2-4x+3\:-\left(2x^2-6x-4\right)](https://tex.z-dn.net/?f=4x%5E2-4x%2B3%5C%3A-%5Cleft%282x%5E2-6x-4%5Cright%29)
Distribute the Negative Sign
![=4x^2-4x+3+-1\left(2x^2-6x-4\right)](https://tex.z-dn.net/?f=%3D4x%5E2-4x%2B3%2B-1%5Cleft%282x%5E2-6x-4%5Cright%29)
![=4x^2+-4x+3+-1\left(2x^2\right)+-1\left(-6x\right)+\left(-1\right)\left(-4\right)](https://tex.z-dn.net/?f=%3D4x%5E2%2B-4x%2B3%2B-1%5Cleft%282x%5E2%5Cright%29%2B-1%5Cleft%28-6x%5Cright%29%2B%5Cleft%28-1%5Cright%29%5Cleft%28-4%5Cright%29)
![=4x^2+-4x+3+-2x^2+6x+4](https://tex.z-dn.net/?f=%3D4x%5E2%2B-4x%2B3%2B-2x%5E2%2B6x%2B4)

![\frac { 3 }{ 8 } \cdot \frac { 4 }{ 9 } =\frac { 12 }{ 72 }](https://tex.z-dn.net/?f=%5Cfrac%20%7B%203%20%7D%7B%208%20%7D%20%5Ccdot%20%5Cfrac%20%7B%204%20%7D%7B%209%20%7D%20%3D%5Cfrac%20%7B%2012%20%7D%7B%2072%20%7D%20)
3 groups of 4/9 means , 3 times 4/9
![3\cdot \frac { 4 }{ 9 } =\frac { 3\cdot 4 }{ 9 } =\frac { 12 }{ 9 }](https://tex.z-dn.net/?f=3%5Ccdot%20%5Cfrac%20%7B%204%20%7D%7B%209%20%7D%20%3D%5Cfrac%20%7B%203%5Ccdot%204%20%7D%7B%209%20%7D%20%3D%5Cfrac%20%7B%2012%20%7D%7B%209%20%7D%20)
Now let's divide this divide by 8.
![\frac { \frac { 12 }{ 9 } }{ 8 } =\frac { 12 }{ 9 } \cdot \frac { 1 }{ 8 } =\frac { 12\cdot 1 }{ 9\cdot 8 } =\frac { 12 }{ 72 }](https://tex.z-dn.net/?f=%5Cfrac%20%7B%20%5Cfrac%20%7B%2012%20%7D%7B%209%20%7D%20%20%7D%7B%208%20%7D%20%3D%5Cfrac%20%7B%2012%20%7D%7B%209%20%7D%20%5Ccdot%20%5Cfrac%20%7B%201%20%7D%7B%208%20%7D%20%3D%5Cfrac%20%7B%2012%5Ccdot%201%20%7D%7B%209%5Ccdot%208%20%7D%20%3D%5Cfrac%20%7B%2012%20%7D%7B%2072%20%7D%20)
As you can see when we divided 3 groups of 4/9 we got the same result as 3/8 x 4/9
Answer:
7200
Step-by-step explanation:

900 x 8 =7200
Answer: -3
Step-by-step explanation:
2 + 3(x) = -7
-2 -2

3x = -9
x = -3
7*7*7 = 343
-> the box is 7 in tall
