Step-by-step explanation:
Since it is a right-angled triangle,
we have a² + 5² = 13². (Pythagoras' Theorem)
=> a² = 13² - 5² = 144, a = 12. (C)
2400 I'm pretty sure that's correct
Answer:
Step-by-step explanation:
i think it is C or B
I will assume that everything after the radical sign is under the sign...
6√(64x^4y^2)
6√(8^2(x^2)^2(y^2)) removing all of the perfect squares...
6*8*x^2*y
48x^2y
