Explanation: Savannas are tropical grasslands with scattered trees, found in Africa, South America, and parts of Asia. They have a distinct wet and dry season.
If x, y and z are real numbers such that (x-5)2+(y-8)2+(z-12)2= 0 then (x+y+z) is equal to
If x2 – 5x + 1 = 0, then find the value of {x2 + (1/x2)}.
If cos(A - B) =√3/2and cot(A + B) = 1/√3, where A - B and A + B are acute angles, then (2A - 3B) is equal to:
If a + b + c = 6, a³ + b³ + c³-3abc = 342, then what is the value of ab + bc + ca
If a + (1/a) = 2, then find the value of (a5 + a3 + 6)/(7a – 5).
What is the value of (a² + b²+4c²- ab-2bc-2ca) (a + b+2c):
(123×123×123 + 130×130×130)/(123×123 - 123×130 + 130×130) = ?
A takes 8 hours more than the time taken by B to cover a distance of 160 km. If A doubles his speed. he takes 3 hours more than B to cover the same dist...
