Choose the simplified form of the fifth term of 6C4(2x)2(-y2)4.

Katarina [22]

You didn't give us the choices. It doesn't matter. I think you're trying to write

$\displaystyle {6 \choose 4} (2x)^2 (-y^2)^4$

$= \dfrac{6!}{4! 2!} ( 4x^2 y^8)$

$= \dfrac{6(5)}{2} ( 4x^2 y^8)$

$=60x^2 y^8$

Answer: 60 x² y⁸

Given,

The angle is 63°

To find the value of z

We know that the diagonals of rhombus perpendicularly bisect each other.

Again,

z+63°+90° = 180° [ sum of all the triangle is 180°]

or, z = 27°
