Answer:

(x^2-4)(x^2-1)

Step-by-step explanation:

Here, we want to factorize the given expression

x^4 - 5x^2 + 4

x^4 - x^2-4x^2 + 4

= x ^2(x^2 - 1)-4(x^2-1)

= (x^2-4)( x^2-1)

The answer to this question would be 39..here is why:

First you multiply 23 x 3..because multiplication or division always comes before addition or subtraction.

Second, you get the product from 23 x 3 which is 69..and you subtract 30 from that.

Last, after you do that you get an over all answer of 39..

20+5=25 then 25-4.67=20.33 so then you do 20.33/4.5=4.5 so the cost for one pound of fruit is $4.57. Hope this helps :)
