1. Find the greatest common factor (GCF)
What is the largest number that divides evenly into 4x^2, -16x^4, and 10x^5?
It is 2.
What is the highest degree of x that divides evenly into 4x^2, -16x^4, and 10x^5?
It is x^2.
Multiply the results above, the GCF = 2x^2
2. Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
2x^2(4x^2/2x^2 + -16x^4/2x^2 + 10x^5/2x^2)
3. Simplify each term in parentheses
2x(2-8x^2+5x^3)
Have a nice day :D
Answer:
$817.50
Step-by-step explanation:
Hello Matt7151!
To find the total amount, we will first need to find how much tax.
We can express 9% as the fraction 
.
× 750 = 67.50
So she's paying $67.50 sales tax.
750.00
67.50
-------------------
817.50
So Debra's really paying $817.50.
Thus, the answer is 
.
If his 1st stroke went 4/5 of the way to the hole, that means the 2nd stroke was 1/5 of the distance. Since we know that the 2nd stroke was 79 meters, we can use this to find the distance from where he started...
If 1/5 = 79 meters then
4/5 = 79 × 4 = 316 meters
Since 1/5 + 4/5 = 5/5 = 1 then 79 m + 316 m = 395 meters for the total distance.
But wait! There's more. The question asks how many kilometers the hole is from where he started... there are 1000 meters per kilometer so...
395 m × 1 km/1000 m =
395/1000 m = .395 km
Total distance from start to hole is .395 km
Yay!!
The determinat of
| a b |

|c d |
is: a*d - b*c
So the determinant of:
|3 -5 |
| |
|1 1 |
is 3 * 1 - 1 * (-5) = 3 + 5 = 8
