Simplify the polynomial (4n² + 3n – 5) − (2n² + 3n<br> -<br> + 6)

Veseljchak [2.6K]

Answer:

2n² + 1

Step-by-step explanation:

Given polynomial:

(4n² + 3n – 5) − (2n² + 3n - 6)

Solution:

Removing parentheses,we obtain

$4n {}^{2} + 3n - 5 - 2n {}^{2} - 3n + 6$

Combine like terms:

$4n { }^{2} - 2n {}^{2} + 3n - 3n - 5 + 6$
$2n { }^{2} + 0 + 1$
$\boxed{2n {}^{2} + 1}$

Done!

Triangular prism
length of slanted side:
sqrt(3^2 + 4^2) = 5
SA = 2(1/2)(8)(3) + 8(12) + 2(5)(12) =240
V = (1/2)(8)(3)(12) = 144

cuboid
SA = 2(7x6) + 2(7x5) + 2(6x5) = 214
