Answer:
(√3-√6) / (√3+√6)
Step-by-step explanation:
The perimeter is 320. Just multiply 80 times 4
substitute the ordered pair (2, 3 ) into the 2 equations
(3 × 2 ) + (4 × 3 ) = 6 + 12 = 18 → True
(2 × 2 ) - (2 × 3 ) = 4 - 6 = - 2 → False
Hence the ordered pair (2, 3 ) is not a solution to the system of linear equations.
When (2, 3 ) is substituted into the first equation, the equation is true.
When (2, 3 ) is substituted into the second equation, the equation is false.
99,999,999 + (-4) is basically 99,999,999 - 4
99,999,999 - 4 = 99,999,995
