Answer:
9,400
Step-by-step explanation:
12,846 - 3,467 = 9,379
The hundreds digit is 3.
So, you look to the left of the digit and if it is 5 for more you add a number to the 3 and make the rest of the digits 0s. But if it below 5, then you leave the 3 alone and make the rest of the digit going to the right 0s.
Then, your answer is (9,400)
Hope this helps ; )
If you are trying to find the area of the triangle, you would do base x height.
14 x 5
So the answer would be 70

Answer:
There are no positive roots
Step-by-step explanation:
The Descartes' rule posits that, given a polynomial with real coefficients ordered, the number of positive roots is equal to the amount of sign-changes OR to such amount minus a number multiple of 2. In you polynomial P(x)=x^3+6x^2+9x+5 you have NO sign-changes, as every coefficient is positive. So, we can confirm that, if the polynomial has real roots, none of these are positive. As 0 can'y be a root of P(x) (replace x=0 and confirm), if there is some root, it will be a negative root. However, the rule can't confirm that there are roots.
Answer:
- 91 meters
Step-by-step explanation:
Sea level is always represented as 0 so if the hiker were to descend to sea level he would go down 91 meters since they are already 91 meters above sea level.
You need to find out how many meters the hiker is from sea level and in this case they are 91 meters above sea level.
You can also write this as an addition problem by saying 91 + -91 = 0
91 is negative since the hiker is descending so they are going down 91 meters.
