You should use your calculator for such simple sums. It is far quicker and involves fewer key depressions than posting the question on WA. But since you seem unable to carry out even this simple task, the answer is 24.5
(49 x 48 x 47 x 46 x 45)/(5 x 4 x 3 x 2) = (49!)/(44!)(5!) = 1,906,884
49 same as positive seven squared
This is called an inequality. If x squared is greater than or equal to 49, then x is plus or minus 7 or greater than plus 7 or less than - 7.
(x-7)2
7 groups of 7 times table for 7s 7 x 1 = 7 7 x 2 = 14 7 more and more and more. answer: 7 x 7 = 49
49 + 2 + 7 = 58 49 x 2 x 7 = 686 49/2 + 14/2 = 63/2 or 31 and 1/2 49/2 x 7 = 343/2 or 171 and 1/2
1, 7, 49 7 is prime.
2 x 2 x 2 x 2 x 2 = 32 7 x 7 = 49 3 x 3 x 7 = 63 2 x 2 x 5 x 5 = 100 49 has the fewest prime factors. 32 and 49 have the fewest distinct prime factors.
1 x 98, 2 x 49, 7 x 14, 14 x 7, 49 x 2, 98 x 1 = 98
98 = 1 x 98, 2 x 49, 7 x 14, 14 x 7, 49 x 2, 98 x 1
2 x 50 = 100 2 x 49 = 98 99 - 98 = 1 Answer: 49 times with 1 remaining
49 = (±7)2 x2<=49 => -7 <= x <= 7
1 x 49, 7 x 7
To find the GCF of two or more numbers, find the factors of each and choose the greatest one. 14 1 x 14 2 x 7 49 1 x 49 7 x 7 The factors of 49 are 1, 7, 49. 98 1 x 98 2 x 49 7 x 14 The factors of 98 are 1, 2, 7, 14, 49, 98. The GCF is 49.
1because:49 = 7 x 7100 = 2 x 2 x 5 x 5the two have no common factors
Adding -4 x -2 and -7 x 7 results in -8 + -49, which simplifies to -57.
These numbers have no common factor (7 x 7 and 2 x 2 x 2 x 2 x 2 x 2) so LCD is 49 x 64 ie 3136.
