Simultaneous Equations (Reducible to Quadratics)?
We were doing equations reducible to quadratics and i got this question, i got this and have no idea what to do.
I DO NOT UNDERSTAND WHY THE ANSWER I
I can seem to get this !
Convert -60 to radians express the answer as a multiple of x.
The answers can be
1.Π/5
2.- Π2
3 .- Π/4
4. - Π/3
Thank you!-To convert degrees to radians, multiply by π/180.
So I need to factor these and Im having trouble help please
81x^4-16y^4
And
s^4-625t^4-81x^4 - 16y^4 = (9x^2 + 4y^2) (9x^2 - 4y^2). That further simplifies to:
(9x^2 + 4y^2) (3x + 2y) (3x - 2y)

Joe wants to build a swimming pool surrounded by a side walk of uniform width. He wants the dimensions of the pool and sidewalk to be 16 meters by 20 meters. The poll has an area of 192 square meters.
The Problem is 2i^2 + 5. Starting with i = 1 and ending with i = 50. I need to find the partial sum but I dont want to just add everything with the series from 1 to 50-This can be broken down to: 2(Su

Convert each point from rectangular form to polar form:
a. (-1,1)
b. (-3,4)-a. (-1,1) responds to -1 + i. First we find the magnitude:
|-1 + i| = √(1+1) = √2

y = the square root of (X + 2)
if you plug in the value 2 for X,
y will equal either -2 or 2.
I thought functions have only one y value for every x value.-as far as I can tell you are correct and thi

Definition: Let G be a group with operation *. we say H is a subgroup of G if
(i) Ø ≠ H ⊂ G,
(ii) g * h ∈ H for all g, h ∈ H, and
(iii) gi ∈ H for all g ∈ H. (gi is the inverse of g).
(a) Prove that
