Find an explicit formula for the arithmetic sequence -11, -3, 5, 13, b(n)= I would appreciate a step by step of the shown work. I struggle with problems like these as well an explanation because for whatever reason arithmetic sequence confuses me and I've never been good at patterns in math. thanks in advance.

Simplify the expression and find the missing terms. the simplest form of has in the numerator and in the denominator.

A. 127 cm^2 b. 144.5 cm^2 c. 172 cm^2 d. 50 cm^2

10 points? ? +++ me asap gabriella uses the current exchange rate to write the function, h(x), where x is the number of u.s. dollars and h(x) is the number of euros, the european union currency. she checks the rate and finds that h(100) = 7.5. which statement best describes what h(100) = 75 signifies? a) gabriella averages 7.5 u.s. dollars for every 100 euros. b) gabriella averages 100 u.s. dollars for every 25 euros. c) gabriella can exchange 75 u.s. dollars for 100 euros. d) gabriella can exchange 100 u.s. dollars for 75 euros.
