1 lb for 2.50
3 lbs for 4.25......4.25/3 = 1.42 per lb
5 lbs for 7.20......7.20/5 = 1.44 per lb
10 lbs for 15........15/10 = 1.50 per lb

The better deal (the cheapest one) = 3 lbs for 4.25 <==

Does anyone have the answers for the rest of this or know the answers ?

irga5000 [103]

Answer:

a) $4x^4-4x^3-16x^2+16x$

b) $4x^4-4x^3-16x^2+16x$

5. Yes

Step-by-step explanation:

The distributive property is:

$(a+b)(c+d)=ac+ad+bc+bd$

It can be extended to a lot of terms as well.

We will use this to multiply both of the probelms shown.

4 a)

$(4x^2-4x)(x^2-4)=(4x^2)(x^2)-(4)(4x^2)-(4x)(x^2)+(4x)(4)=4x^4-16x^2-4x^3+16x=4x^4-4x^3-16x^2+16x$

The answer is $4x^4-4x^3-16x^2+16x$

4 b)

$(x^2+x-2)(4x^2-8x)=(x^2)(4x^2)-(8x)(x^2)+(x)(4x^2)-(8x)(x)-(2)(4x^2)+(2)(8x)=4x^4-8x^3+4x^3-8x^2-8x^2+16x=4x^4-4x^3-16x^2+16x$

The answer is $4x^4-4x^3-16x^2+16x$

5. Yes
