What is the simplified form of the expression(x + 6)(7x − 1)? 8x^2 + 5

7x^2 + 41x − 6

7x^2 + 43x − 6

7x^2 − 6

Aparallel system functions whenever at least one of its components works. consider a parallel system of n components, and suppose each component works independently with probability 0.5. find the conditional probability that component n works given that the system is working

What’s -11-33k and factor each expression completely

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
