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 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
49 x 49 = 492 = 2401
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
The number of times that 2 can go into 99 evenly is determined by dividing 99 by 2. This division results in 49 with a remainder of 1. Therefore, 2 can go into 99 a total of 49 times with a remainder of 1.
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
We will do this in steps. -4 x -2 = 8. -7 x 7 = -49. 8 + (-49) = -41.
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.
