Ive been out of school too long and cant remember how to answer this. As far as I can get is:

(X * Y) = [(Z*X) + (Z*Y) + (Z^2)]

XY = Z(X + Y + Z)

I just can't figure out the right move to get Z by itself.

I mean, sometimes we can work around it, but other times the use of subscripts, superscripts and special symbols is actually necessary.

Interpreting questions can be a little confusing, and sometimes they can be misinterpreted. But more importantly, it is necessary that the asker gets a CLEAR answer, otherwise the whole asking - answering process is futile if not even harmful.

Well I hope this doesn't go unread

This plant grows about 1 inch tall, and creeps along the ground. It grows very well in shade and almost as well in sun. It grows well in poor soil. Floods from poor drainage don't bother it. Its flowers are very different than ordinary white clover flowers. They're more like ordinary garden flowers, with ordinary petals, except that they're much smaller, and are a very pretty bright blue-violet color. They start blooming when the ground thaws in the spring, and bloom for about two months. The leaves are close to the size and color of clover leaves.

If you don't know what plant it is, do you know an online reference that could help identify it?

Does anyone know how to do this

A circuit having a resistance of 12 ohm, an indutance of 96mH and a capacitance of 52mF in series, is connected across a 220V, 50Hz supply. Calculate the following:

Total Impedance

current flowing through the circuit

the voltage across each component

the phase difference between the current and the supply voltage

The power factor of the circuit

I'm confused about the location of methane hydrates deposits - on the one hand i've read they are mostly found within the sediments of continental shelves, which depth is useully around 300m, yet i've also heard the hydrets are most common at the depths of 1000m below surface.

(From the diagrams i've seen it doesnt seem as if the deposits are 700m beneath the continental shelve's sediment- they are drawn as a thin layer- and to add to the mess - some sources claim the hydrates are at the ocean floor,1000m below sea surface!)

links will be really apprecited :)

thanks!

Did anyone else see this? It was around 10:00 P.M. and later.
I tried to film it but they were not bright enough to be caught on cam corder. They would have been in the Northern sky. My hubby saw it too and at first tought it was a search light. There was no lights beaming from the earth up. It was just inside the cloud or above it.

a. f(x) = (x + 1)/(2x + 4)

b. g(x) = 2x/(x2 - 4)

c. h(x) = (x2 + 4x + 15)/(x + 2)

d. F(x) = (x3 - x - 1)/[(x - 1)(x + 2)]

e. G(x) = (x3 )/(x - 4)

f. none of these
