Question

It If m=2 and n=3 then 10m²-9n²=77. justify your answer.
​

Answer 1

We can solve this by simply substituting the values in the equation:

We have:

$m = 2\\n = 3$

Substituting values of m and n into the equation:

$10(2)^2 - 9(3)^2 = 77$

Solving:

[tex]10*4 - 9*9 = 77\\ 40 - 81 = 77\\ -41 = 77\\ [/tex]
As we have arrived at a false statement, we can conclude that the equation was false.

So, for m = 2, n = 3, 10m²-9n² ≠ 77

Hope this helped!

Answer 2

Answer:

10(2)²-9(3)²=77

40-81=77

41 not equal to 77
