Answer:
40
Step-by-step explanation:
Because this is a 45-45-90 triangle, the two smaller sides are equal to each other. After you find one of them, square it, then divide by 2.
Step-by-step explanation:
4x2 - 25b2
We can solve it by the squares so
(2x - 5b) (2x + 5b)
2) x2 - 81
The same case is here so
(x - 9) (x + 9)
