Answer:
so 5 miles upstream and 15 miles downstream
Step-by-step explanation:
25/5=5
30/2=15
X+3+2x+1+3x-4=180(the sum of all angles of a triangle is always 180 )
so 6x=180
x=30
x+3=33
2x+1=61
3x-4=86 are the required anglea
Hi! Your answer is 13.
All you have to do is divide 52 by 4. When you do this, you will find how many laps they walked per hour.
(They walked 52 laps in 4 hours)
52 / 4 = 13
They walked 13 laps in one hour.
Hope this helped!
Answer:
–√(7) must also be a root of f(x)
Step-by-step explanation:
Given that the roots of an equation is 3 and √(7). This means that x = 3 or √(7). Therefore, the function is definitely going to be:
f(x) = (x – 3)(x² – 7)
This is because we are dealing with √(7) and what brought about √(7) was x² = 7.
If this is the case, we know that x² = 7 will give
x = ±√(7)
Hence, our roots are x = 3 or √(7) or –√(7). Therefore, –√(7) must also be a root of f(x).
