Answer:
The two numbers are 8 and 5.
Step-by-step explanation:
Let consider x and y to be these two numbers.
So;
(x) * (y) = 40 ---- (1)
x + y = 13 ----- (2)
From (2), let x = 13 - y
Then;
(13 - y) * y = 40
13y - y² = 40
13y - y² - 40 = 0
-y² + 13y - 40 = 0
Multiply through by (-)
y² - 13y + 40 = 0
By factorization;
(y - 8) (y - 5) = 0
y = 8 or y = 5
CHECK:
8 * 5 = 40
8 + 5 = 13
Therefore, the two numbers are 8 and 5.
