The product of any two numbers is composite ( true/false) and why?
Reptile [31]
<u><em>FALSE.</em></u><em></em> 
A composite number is the opposite of a prime number. This is false because of the possibility of the following scenario:
The two numbers are 1 and a prime number.
This is because <em>one multiplied by any number is that number.</em> A prime number cannot become a composite number just because it is being multiplied by one. For example:
1 x 7 = 7 (prime) 
Hope this helps!

The sum of two numbers is 23. The difference of the numbers is 7.4. What are the two numbers?​
Brums [2.3K]
X+y=23
X-y=7.4

X+y=23
y=23-X

X-y=7.4
(23-y)-y=7.4
23-2y=7.4
-2y=-15.6
Y=7.8

X+y=23
X+7.8=23
X=15.2

Therefore the two numbers are 7.8 & 15.2
