Answer:
False
Step-by-step explanation:
It’s B !!!!!!!!!!!!!!!!!!!!!!
Xy = 50
x + y = 15
x = 15 - y
xy = 50
(5 - y)y = 50
5y - y^2 = 50
y^2 - 5y + 50 = 0
(y - 5)(y - 10) = 0
y - 5 = 0 or y - 10 = 0
y = 5 or y = 10
x + y = 15
For y = 5:
x + 5 = 15
x = 10
For y = 10
x + 10 = 15
x = 5
Answer: the numbers are 5 and 10.
The first one! It is using the distributive or associative property!
The answer is 5 and 0
(-5) + 5 = 0
