Answer:
t = 1.5 hours
Step-by-step explanation:
Given that,
A man walk for 2hr at 6 km/h.
He then cycled for a certain time at 16 km/h.
He travelled 36 km all together.
We need to find for how many hours did he cycle.
Distance walked in 2 hours = 2×6 = 12 km
Distance he cycled = 36-12 = 24 km
Let he cycled for t hours. So,
So, he cycles for 1.5 hours.
When we simplify (3 + √5)(3 + √2), the result obtained is:
9 + 3√2 + 3√5 + √10
<h3>Surd operation </h3>
a√b × c√d = (a × c)√(b × d)
<h3>How to simplify (3 + √5)(3 + √2)</h3>
(3 + √5)(3 + √2)
Expand by clearing the bracket
3(3 + √2) + √5(3 + √2)
9 + 3√2 + 3√5 + √10
Thus,
(3 + √5)(3 + √2) = 9 + 3√2 + 3√5 + √10
