Answer:
BC = 26
Step-by-step explanation:
Given that:
B is the midpoint of AC
Then AC = AB + BC
AC = 8x - 20 and AB = 3x - 1
Then,
8x - 20 = (3x - 1) + BC
8x - 20 - (3x - 1) = BC
8x - 20 - 3x + 1 = BC
5x - 19 = BC
But AB = BC
5x - 19 = 3x - 1
5x - 3x = - 1 + 19
2x = 18
x = 9
Hence,
Since BC = AB = 3x - 1
3(9) - 1
27 - 1
= 26
Answer:
We are given eqaution: e=\frac{17}{20}d , where e the amount of euros and d is the value as U.S. Dollars.
We need to find number of euros for 1 U.S. Dollar.
Plugging d=1 in the given equation
We get
e=\frac{17}{20}(1)
On simplfying , we get
e=\frac{17}{20}
Dividing 17 by 20, we get 0.85.
Therefore, there would be 0.85 euro have the same value as 1 U.S. Dollar.

Step-by-step explanation:
The correct answer would be 2x2+ 7x + 1, 3x2 + 8 and x2 + 36. These polynomials cannot be reduced to a lower degree where the factors are integers so they should be prime. The factors are as follows:
