Simplify:
1. x[2x+5(3x+9)] =
2. 4a(a-3)-a2+4= (its supposed to be a squared "a2")
3. x[2x+3 x 18]= (note its 3 times 18)

Ok! On number 1 if you multiply x[2x....] does that equal 2x or is that 3x? I can't remember. On number 2 the part where it says 4a(a-3)... I know you use the distributive property but does that equal 4a-12 or is that like 4a(squared)-12?

please show me how to do the problem! ^_^ thanks

When you have problems that involve a less than sign or a greater than sign, I know that it's crucial to express your answer in a certain way. I know it involves the concept of and vs or, and I know the U (and the upside down U) for union are involved. I apology for the lack of clarity of my question, but could someone give me some guidance here? Thanks!

A train moving with a constant velocity travels 180 m north in 12 s and an undetermined distance to the west. The speed of the train is 22 m/s.

How far west has the train traveled in this time?

An infinite sheet of charge, oriented perpendicular to the x-axis, passes through x = 0. It has area density s1 = -4 µC/m2. A thick, infinite conducting slab, also oriented perpendicular to the x-axis, occupies the region between x = a and x = b, where a = 2 cm and b = 3 cm. The conducting slab has a net charge per unit area of s2 = 6 µC/m2.

(a) Calculate the net x-component of the electric field at the following positions:

At x = -1 cm
At x = 1 cm:
At x = 6 cm

(b) Calculate the surface charge densities on the left-hand (sa) and right-hand (sb) faces of the conducting slab.

I was watching something last night but I fell asleep and forgot to record it. It might have been called "How Earth was Made." On TLC or NGC.
They had a graphic of early earth playing through and the time line started at 4.6 bya. I saw 1.5 when oxygen and then water was abundant.
Are there any ideas of what land was like then? Fossils? Where is this land positioned now on the globe if it even exists any longer?

A roller coaster moves 200 ft horizontally, then rises 135 ft at an angle of 30.0° above the horizontal. Next, it travels 135 ft at an angle of 40.0° below the horizontal. Use graphical techniques to find the roller coaster's displacement from its starting point at the end of this movement.

magnitude ft
