Answer:
33
Step-by-step explanation:
let the shorter piece be x m
then the longer piece is 41-x
"The short piece is 25 meters shorter then the long piece"
or
the difference between the longer and the shorter is 19
--->
(41-x) - x = 25
41-x-x = 25
-2x = 25-41
-2x = -16
divide both sides by -2
x = 8
I defined x to be the short piece ---- 8
I defined 41-x to be the longer --- 41-8 = 33
In math, equivalent means equal to.
Answer:
the answer to the question is 8x⁴- 5x²y² - 6y⁴
Step-by-step explanation:
the normal way of using BODMAS is apply to all polynomial equations.
subtracting -6x⁴- 3x²y² + 5y⁴ from 2x⁴ - 8x²y² - y⁴.
polynomial of the same degree is very easy to calculate. this equation is having the same degree of polynomial all through, therefore:
Applying Bracket to the equation
2x⁴ - 8x²y² - y⁴- ( -6x⁴- 3x²y² + 5y⁴)
Open the bracket
2x⁴ - 8x²y² - y⁴ +6x⁴+3x²y² - 5y⁴
collects the likes terms
2x⁴ +6x⁴- 8x²y² +3x²y² - 5y⁴ - y⁴
The final answer is =
8x⁴- 5x²y² - 6y⁴
