4x-3(-2)=18
multiply the -3 by the -2 to get 4x+6=18
Subtract the 6 from both sides to get 4x=12

Which of the following is a factor of x^6 + 1000?

Lena [83]

Well,

$x^6+1000=(x^2)^3+10^3$

From here we use $a^3+b^3=(a+b)(a^2-ab+b^2)$ ,

$(x^2+10)\boxed{(x^4-10x^2+100)}$

And the found our factor.

Hope this helps.

UkoKoshka [18]

Answer:

New cut off salary = 30,592

Step-by-step explanation:

Given:

Normal distributed mean = $37,000

Standard deviation = $5000

Cut off salary = 10%

Find:

New cut off salary

Computation:

Z - left tale value of 10% is -1.2816

Corresponding x-value using x = zs + u

New cut off salary = (-1.2816)(5,000) + 37,000

New cut off salary = -6,408 + 37,000

New cut off salary = 30,592
