10x^2 − 9y^2 is not the difference of two squares. identify the correct explanation for this statement. a neither 9y^2 nor 10x^2 are perfect squares. b 10x^2 is not a perfect square. c 9y^2 is not a perfect square. d both 9y^2 and 10x^2 are perfect squares.

B

Step-by-step explanation:

9y² is a perfect square since = 3y

10x² is not a perfect square since = x

yes because a quadrilateral is equal to 4 sides and a rhombus has 4 sides so technacly it is a quadrilateral.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
