Answer: 6 and 7 Step-by-step explanation: Let us say that the numbers are x and y. Then, x + y = 13 So, y = 13 – x xy = 42 So, x(13 – x) = 42 13x – x^2 = 42 x^2 – 13x + 42 = 0 x^2 – 7x – 6x + 42 = 0 x(x – 7) – 6(x – 7) = 0 (x – 7) (x – 6) = 0 x = 7 or 6. So, y = 6 or 7. So, the numbers are 6 and 7. Reply

Answer:
6 and 7
Step-by-step explanation:
Let us say that the numbers are x and y.
Then, x + y = 13
So, y = 13 – x
xy = 42
So, x(13 – x) = 42
13x – x^2 = 42
x^2 – 13x + 42 = 0
x^2 – 7x – 6x + 42 = 0
x(x – 7) – 6(x – 7) = 0
(x – 7) (x – 6) = 0
x = 7 or 6. So, y = 6 or 7.
So, the numbers are 6 and 7.
Answer:
the no.s are 6 & 7
because
6+7 =13
6×7=42
