**partial fractions**

(7x^2-16)/(x^2-2x) solve by using partial fraction decomposition. i cant figure out how to do this because after i split up the bottom the A and B dont end up having an x^2 in order to equal the numerator of the original fraction. so confused!

**pre calc**

Find the values of b such that the system has one solution. x^2 + y^2 = 36 y= x+b and then they give me an answer box b=_________ (smaller value) b=_________ (larger value) i have absolutely no idea how to even begin this and what they are asking. could some please help and ex...

**PRE CALC**

yes but i still dont get the answer!!!

**PRE CALC**

Use matrices to solve the system. (If the system has infinitely many solutions, express your answer in terms of c, where x = x(c), y = y(c), and z = c. If the system has no solution, enter NONE for each answer.) 5x+2y-z=2 x-2y+2z= -1 3y+z= -17 ive done tons of these but this o...

**algebra 2**

i got 5(w^2-7w+12)=0...is that right?..and then do i factor the middle?...but when i did i get 3 answers

**algebra 2**

how do u factor 5w^2-35w+60=0 if u could...can y plz explain it..i keep getting 3 ansers instead of 2

**algebra 2**

omg thnx

[=absolute value [-2x+1]>2 ok im doin inequalities and the only thing i dont get is if i take the absolute value off the -2x+1 goes to 2x+1 right?

**math**

all u do is 42x2 which is 84. then u subtract 84 from 108 and divide it by 2. the width is 12.
