10 - 3 = 7 and 10 x 3 = 30
The product of a sum and a difference with 31 times 29 is:(30+1) x (30-1)sum to differencemakea product= 30² - 1²= 900 - 1= 899
(+7 and +8) and (-7 and-8)
14 and 2
Product means multiplication 3 x 7 = 21 Sum means the addition 3 + 7 = 10 Difference means subtraction Hence 21 - 10 = 11 The answer .
30 - 11 = 19
10 and 3
3 and 10 is one answer. The other answer is -3 and -10.
30*7 = 210
The product of a sum and a difference with 31 times 29 is:(30+1) x (30-1)sum to differencemakea product= 30² - 1²= 900 - 1= 899
5 x 7 = 35 Therefore, the product is 5 more than 30!
(+7 and +8) and (-7 and-8)
11 and 7
No. 30 x 7-3 = 120 27 x 7 = 189
.82
7 is the product of the sum 16-9
23
30 x 10 = 300. 75 + 75 = 150. Their difference is 150.
