Your answer here would be A. because every hour she travels 3 miles so 3h. (3 × h). Then you add the 5 miles you know she at least walked. Put it together and you get 3h + 5. Hope this helped :)
Greater than because they are negative
Answer:
The length of BC is 17
Step-by-step explanation:
When we construct a triangle with the data, we will end up a isosceles triangle.
In a isosceles triangle , we know that tow angles and two sides are equal
The questions states that

Then sides AC and AB are also equal
On equation their values
2X - 8 = X+9
2X = X + 9 +8
2X = X + 17
2X - X = 17
X = 17
The length of BC = X = 17
