b)True
c)False
d)True
e)True
Step-by-step explanation:
a) False
No it is not true for all cases
Ex
2 x = 5 ------1
3 x =7.5 ------2

b)True
If a linear system has free variables, then it must have infinitely many solutions.
c)False
Every linear system with the same number of equations and variables has a unique solution.This is not true for all cases.
d)True
In every linear system with 2 equations and 3 variables x1,x2,x3, the last variable x3 is a free variable.
e)True
If x1 = x2 = ··· = xn = 0 is a solution to a linear system, then the system must be homogeneous.

ANSWER
Each side of the chip is 5 centimeters long.
<u>EXPLANATION</u>
The chip is in the form of a square.
The formula for finding the area of a square is
We were given in the question that, the area is 25 square centimeters. This means that,
We take the square root of both sides to get,
Hence the length of the square technology chip is 5 centimeters
