It is 7*13 = 91
91
7 and 13. Solution : Let the two numbers be a and b. Then ab = 91 , so b = 91/a. a + b = 20 .......substituting for b, this becomes : a + (91/a) =20 Multiplying both sides by a gives : a2 + 91 = 20a Rearranging : a2 - 20a + 91 = 0 Factoring gives : (a - 7)(a - 13) = 0 Then the numbers occur when x - 7 = 0. → x = 7, and when x - 13 = 0. → x = 13.
Assuming you mean 20 instead of 120, 13 and 7.
Their product.
7 x 13 = 91
14 multiplied by 91 is 1,274.
It is: 7 times 13 = 91
The product of 7 and 13 is 91
