If a b and a c then a bc
Web16 mrt. 2024 · Transcript. Example 1 If A, B and C are three points on a line, and B lies between A and C then prove that AB + BC = AC. In the figure given above, AC coincides with AB + BC. From Euclid’s Axiom 4 : Things which coincide with one another are equal to one another. So, we can write AB + BC = AC. Next: Example 2 Important → Ask a doubt. Web29 mrt. 2024 · (iii) If A ⊂ B and B ⊂ C, then A ⊂ C Let A = {1}, Since, A ⊂ B, all elements of set A i.e. 1 should be an element of set B Hence, taking B = {1,2} Also, B ⊂ C, all elements of set B i.e. 1,2 should be an element of set C Hence, taking C = {1,2,3} ∈ - (belongs to) element in set ⊂ - is a subset A ⊂ B if all elements of A are in B We have to prove …

Web1 aug. 2024 · Solution 1. of a c > b c, it follows that a c − b c > 0 and ( a − b). c > 0. Knowing that the data numbers x, y ∈ Z, such that x. y > 0, then x and y are either positive or negative, i.e, x, y > 0 or x, y < 0. By hypothesis, c > O, and so a − b > 0. Therefore, a > b, which solves the problem. Web16 jan. 2024 · Best answer Correct option (C) Both (A) and (B) As a b, ,c d, are in HP, b is the HM between a and c. Also the GM between a and c = √ac. Now, GM > HM so that √ac > b ⇒ ac > b2 ..... (1) Again a b, ,c d, are in HP, so c is the HM between b and d. Therefore, bd > c2 ..... (2) Now multiplying Eqs. (1) and (2), we get abcd > b2c2 or ad > bc
