Answer:
5 units
Step-by-step explanation:
Step one:
Given data
Le the first number be x
and the second number be y
So
x*y= 10-----------------1
and
x+y= 7-----------------2
from eqn 1
x= 10/y
put x= 10/y in eqn 2

cross multiply we have

rearrange

the factors of the quadratic expression are
-5 and -2

The longest side is 5 units
If I’m using substitution the answer is A
