Question 170193: Add. Simplify if possible. 7v/v^2-49 + v/v-7 (this is a fraction)
Find the polynomial for the perimeter and for the area z+8 (top of square) z (side of square).
Subtract by simiplifying collecting like radical terms if possible 4 square root sign 80 - 6 square root sign 5.
If the sides of a square are lengthened by 7cm, the area becomes 196cm^2.
Find the length of a side of the oringinal square.
Please help I have to submit by tomorrow.
Thank you in advance

Question 170133: I'm doing long division for division of algebraic expressions and trinomials............ question is ...
_________________
2x^4 + 4x^3 + 2 / x^2 - 1 long division = x^2 - 1 / 2x^4 + 4x^3 + 2
answer is 2x^2 + 4x + 2 and i have no idea how they arrived at that answer??: I'm doing long division for division of algebraic expressions and trinomials............ question is ...

Question 170106: Someone should sue al-khwarizmi or the greeks for even iventing algebra! lol
since i am probably the worst person in my algebra class, i guess i will be coming here more often lol
if someone could help me with these three problems id be very thankful =)
(x+2)(x+3)= x^2+2x+3x+6= 11x^4 (or not?)
(2x-5)(3x+2) (my teacher olny wrote to that; "you should use the foil system")
(2x+5)(x^2-x-2) (I got that one totally wrong, but that was only because i didnt really understand it at all).

Question 170010: Please Help. Thank You.
Increasing cube. Each of the three sides of a cube with
sides of x centimeters is increased by a whole number of
centimeters. The new volume in cubic centimeters is
given by
V(X)= x^3 + 10x^2 + 31x + 30.
a) Find V(3).
b) If the new height is x + 2 centimeters, then what are the
new length and width?
c) Find the volume when x =3 by multiplying the length,
width, and height.: Please Help. Thank You.
