Answer:
x⁴ + 6x² + 9
Explanation:
To answer this question, we will multiply each term from the first bracket by each term from the second bracket and then combine like terms to get the final expression.
This can be done as follows:
(x² + 3)(x² + 3)
x²(x²) + x²(3) + 3(x²) + 3(3)
x⁴ + 3x² + 3x² + 9
x⁴ + 6x² + 9
Hope this helps :)
Answer:
2.99 cm
Step-by-step explanation:
V= 
(pi)(r^3)=113.04cm^3
113.04/ (pi) = r^3 = 26.99
r=![\sqrt[3]{26.99}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B26.99%7D)
= 2.99cm
The answer is C
you would isolate x in the first equation then substitute it in to the second equation and solve for y. then plug y in to the first equation.
x+y-z+w = 10--------(1)
x+3y-4z+5w=26------(2)
x+4y-7z+7w = 37-------(3)
x+2y-3z+6w = 22--------(4)
Subtract equation (1) from (2)
x+3y-4z+5w - (x+y-z+w) = 26 - 10
2y + -3z - 4w = 16-----------------------------(5)
Subtract equation (1) from (3)
the answer to ur question is 18
