9^2 - 6^2 = x^2
81- 36=x^2
x^2 = 45
x = √45
x= √5×3 ×3

ArbitrLikvidat [17]
The first thing we should know in this case is the meaning of the following acronyms:
 (GPA) = Grade Point Average.
 Effectively in a program like excel she can use:
 GPA = (a1 + a2 + a3 + a4) / 4
 Where,
 ai = represents each of the notes (i: 1,2,3,4)
 However, this is also an example of the following type of entry:
 GPA = AVERAGE (a1: a4)
 Answer:
 Entry:
 Formulas: are references of cells, names of cells or ranges, functions or operators that result in a value from other existing values.

What is the complete factorization of 4x2 - 9y4?
Liono4ka [1.6K]

Answer:

<em>the answer is c</em>

( 2 x + 3 y ) ( 2 x − 3 y ) is the factored form of the expression

Step-by-step explanation:

  • 4 x 2 − 9 y 2 can be also written as ( 2 x ) 2 − ( 3 y ) 2
  • Now, as per identity: a 2 − b 2 = ( a + b ) ( a − b )
  • So , in case of our expression a = 2 x , b = 3 y ( 2 x ) 2 − ( 3 y ) 2 = ( 2 x + 3 y ) ( 2 x − 3 y )
