Answer:
20 miles (Answer B)
Step-by-step explanation:
The northbound biker travels (4 mph)(4 hr) = 16 mi, and
the eastbound biker travels (3 mph)(4 hr) = 12 mi.
They travel at right angles to one another. Thus, the Pythagorean Theorem applies here. The distance between the two bikers is d = √( [12 mi]^2 + [16 mi]^2 ), or √(144 + 256) mi, or √400 mi, which works out to 20 miles.
Answer B is correct.
Answer:
3y √21 + 2 y√15
Step-by-step explanation:
To simply, we open up the bracket
We have this as;
√(189y^2) + √60y
= 3y √21 + 2 y√15

Hi,
Answer: D) -216/125
This can be easily solved in 7 easy steps!
<u><em>My Numerical work:</em></u>
1. (-6 / 5) ^3
2. (-6 / 5)^3
3. (-6 / 5) * (-6 / 5) * ( -6 / 5)
4. (-6) * (-6) * (-6) / 5 * 5 * 5
5. (-6)^3 / 5^3
6. -216 / 125
As a decimal it would be:
7. -1.728
I Hope I Helped!
