10 800 0 to the first problem
Answer:
6
Step-by-step explanation:
base + 2(legs) = 56 (2 legs are the same because it's isosceles)
x + 2(5x - 5) = 56
x + 10x - 10 = 56
11x -10 = 56
11x = 66
x = 6
If the matrix is of 2 by 2 then we can find the determinant of the matrix.

Then (ad - bc ) gives you the determinant of the matrix.
For example,

= (2)(-2) - (1)(4)
= - 4 - 4
= -8
