Answer:
The zeros occur when x = -3 , -1 , 1 and 7
Step-by-step explanation:
I don't exactly know how to do this so I can show you how to do it using some sort of method of division. There are 2 huge steps to be taken. Start with 1
Using synthetic division you get
-1 || 1 - 4 -22 4 21
-1 5 17 -21
===================
1 - 5 -17 21 0
So far we have x = - 1 or (x + 1) is a factor.
It turns out by trial and error that x = - 3 is a factor. What you get after that synthetic division is x^2 - 8x + 7 which factors into (x - 7)(x - 1)
So what we get is
(x - 1)(x + 1)(x - 7 )(x +3)
As in this figure two sides of triangle are equal so angle A=B because angle opposite to equal sides are equal so
60+x+x= 180
60+2x=180
2x= 180-60
2x=120
x=120/2
x=60
Therefore B,C is 60
Answer:
The number of dimes is 3n - 8
Step-by-step explanation:
Here, we are interested in writing an expression for the number of dimes.
We proceed as follows;
Now, there are n nickels with the number of dimes been 8 less than 3 times the number of nickels
That would be;
3(n) -8 = 3n -8
Answer:
We can conclude that the distance from Sandy's Hotel to Trader Joes' Store is:
Step-by-step explanation:
From the coordinate plane, we can clearly identify that:
- Sandy's Hotel is located at the point (-8, 9)
- Trader Joes' Store is located at the point (-4, 2)
The distance from Sandy's Hotel to Trader Joes' Store can be calculated such as:
The distance between (-8, 9) and (-4, 2)
miles
Therefore, we can conclude that the distance from Sandy's Hotel to Trader Joes' Store is:
