I believe the answer is 24 : 1
I think that supposed to be (wx - y^2)^2?
If so, multiply using FOIL:
First: wx * wx = w^2x^2
Outside: wx * -y^2 = -wxy^2
Inside: -y * wx = -wxy^2
Last: -y^2 * -y^2 = y^4
Combine w^2x^2 - 2wxy^2 + y^4
The volume of a cylinder is r^2

dh
enter values, then you get 3.53, multiply that by the BTU, the answer is 8888 BTU
Answer:
1. X^2+1/2x = 
2. X^2+2x-3 = 
3. (2x-3)^2 = (2x-3)(2x-3)
4. X^3+2x^2-19x-20 = 
Step-by-step explanation:
Each expression can be written as a product of linear factors as follows
1. X^2+1/2x ⇒ 
= 
Hence, X^2+1/2x = 
2. X^2+2x-3 ⇒ 



Hence, X^2+2x-3 = 
3. (2x-3)^2 ⇒

Hence, (2x-3)^2 = (2x-3)(2x-3)
4. X^3+2x^2-19x-20 ⇒ 

First,

∴ 
Hence, X^3+2x^2-19x-20 =
