Answer:

60

Step-by-step explanation:

60% * x = 45% * 80

Changing to decimal form

.60x = .45 *80

.60x =36

Divide each side by .60

.60x/.60 = 36/.60

x =60

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)

Step-by-step explanation:

What you do first is you have to figure out the 5.99% interest rate.

150 x 5.99 = 8.99

150 + 8.99 = $158.99

Now multiply that by 16

158.99 x 16 = $2,543.84 is your answer.
