Use the proportion 8/64 = 12/y. Cross multiply to get 8y = 768. Divide both sides by 8 to get y=96

Which expression does not factor?<br><br> m3 + 1<br> m3 – 1<br><br> m2 + 1<br><br> m2 – 1
Luda [366]

Answer:

m^2 +1

Explanation:

All the other expressions can be factorized. Let's see why:

1) m^3 +1

This is the sum of the cubes, and this can be factorized as follows:

a^3+b^3=(a+b)(a^2-ab+b^2)

In this case, a=m and b=1, so we can factorize as

m^3+1=(m+1)(m^2-m+1)

2) m^3-1

This is the difference between two cubes, and this can be factorized as follows:

a^3-b^3=(a-b)(a^2+ab+b^2)

In this case, a=m and b=1, so we can factorize as

m^3-1=(m-1)(m^2+m+1)

3) m^2-1

This is the difference between two square numbers, and it can be factorized as follows

(a^2-b^2)=(a+b)(a-b)

In this case, a=m and b=1, so we can factorize as

m^2-1=(m+1)(m-1)

SOVA2 [1]
<h2>Answer:</h2>

The dollars worth of zinc which is contained in hair cut in the United States every year is:

                         $ 2,220,000

<h2>Step-by-step explanation:</h2>

The total kilograms of hair that are  cut in the United States are: 25,000,000 kg

Also, the amount of zinc present in 1kg of hair is: 0.0002 kg

Hence, the amount of zinc present in 25,000,000 kg of hair is:

25,000,000×0.0002=5,000 kg

Also, cost of 1 kg of zinc= $ 444

Hence, cost of 5,000 kg of zinc will be: 5,000×444

Hence, cost of 5,000 kg of zinc=$  2,220,000
