what was the plot for the book twisted?

**algebra 1**

Area = L * W Perimeter = 2L + 2W W = L - 80 So, plug in the width formula into the perimeter equation, which would look like this: 640 = 2L + 2(L-80) 640 = 2L + 2L - 160 640 = 4L - 160 800 = 4L L = 200 It looks like you don't even need the information about the area of the...

**Precalculus**

Yeah it confuses me too :( thanks for your help though, I appreciate it! :D

**Precalculus**

I know i isn't considered a real coefficient, but when you multiply it out shouldn't there be an ix as you're working it out?

**Precalculus**

Write the simplest polynomial equation with real coefficients having roots -i and 4. I have noooooo idea how to even start this one :( I thought you could start backwards with synthetic substitution but it didn't work. Any help on this is greatly appreciated!! :D

**Precalculus**

I'm sorry I'm posting so many questions, I promise this is the last one tonight :) The leading coefficient of a cubic polynomial P is 2, and the coefficient of the linear term is -5. If P(0)=7 and P(2)=21, find P(3). I DO NOT understand how to even start this one. I th...

**Precalculus**

Whoops, I meant we had to find the value of the function K(x^2), not where K(x)=x^2. Sorry about that lol

**Precalculus**

K(x) = x^2(x^2 + 16), where K(x) = x^2. I got K(x^2) = x^8 + 16x^4. Is this right? Thanks :))

**science**

The formula for density is p = m/v, where p is density, m is mass, and v is volume. First, you would figure out the volume by: V = 3 cm * 3 cm * 3 cm V = 27 cubic centimeters Plug everything that you know into the formula: p = 27g / 27cm^3 p = ? g/cm^3 Hope this helps! :)

By the way, in the first problem in the parentheses it's supposed to be like "one minus the square root of 2". Sorry if that wasn't clear :-/

Did I do these two problems right? P(1-sqrt2) = 8x - 4x^2 P(1-sqrt2)= -4 P(2/x)= 8x - 4x^2 P(2/x) = x-1 I think when the answers are plugged back in, the equation is supposed to equal zero, but I don't get this; however, I always redo each problem with different methods an...
