Question

difference between two numbers is 14,and their sum is 20.what will be their product

Answer 1

Answer:51

Step-by-step explanation:let the numbers be x and y

so, x-y=14

x+y=20

now adding both the equations we got 2x=34,x=17

now putting the value of x in first equation we got y=3

so the product is xy=17*3=51

Answer 2

Answer:

51

Step-by-step explanation:

let the numbers be x and y

given that

difference of that numbers = 14

so, x - y = 14 ......(1)

and

sum of that numbers = 20

so, x + y = 20 ......(2)

(1) + (2)

x - y + x + y = 14 + 20

2x = 34

x = 34/2

x = 17

putting the value of x on (1)

x - y = 14

17 - y = 14

-y = 14 - 17

-y = -3

y = 3

so, the numbers are 17 and 3

product of that numbers

= 17 × 3

= 51
