What is represented by p v q?
Stella [2.4K]
\lor is the logical or/disjunction symbol. p\lor q means "p or q". Disjunction is commutative, which means p\lor q is equivalent to q\lor p.

So if p represents x and q represents x>3, then p\lor q\equiv q\lor p means x>3 or x.

Does 3 and the square roots of 8 and 17 form a right triangle
Gala2k [10]
If it’s is a right triangle then
A^2 + B^2 = C^2
3^2 + (square root of 8)^2 = 17^2

I don’t have a calculator but type that in and if it doesn’t equal 17^2 than the answer is no it doesn’t make a right triangle
