Answer:

(4 (x - 1) (x + 3)^2 (x + 2))/5

Step-by-step explanation:

Simplify the following:

(2×4 x (x + 3) (x - 1) (x + 2) (x + 3))/(10 x)

((x - 1)×4×2 (x + 3) x (x + 2) (x + 3))/(x×10) = x/x×((x - 1)×4×2 (x + 3) (x + 2) (x + 3))/10 = ((x - 1)×4×2 (x + 3) (x + 2) (x + 3))/10:

(4×2 (x - 1) (x + 3) (x + 2) (x + 3))/10

The gcd of 4 and 10 is 2, so ((x - 1)×4×2 (x + 3) (x + 2) (x + 3))/10 = ((2×2) 2 (x - 1) (x + 3) (x + 2) (x + 3))/(2×5) = 2/2×(2×2 (x - 1) (x + 3) (x + 2) (x + 3))/5 = (2×2 (x - 1) (x + 3) (x + 2) (x + 3))/5:

(2×2 (x - 1) (x + 3) (x + 2) (x + 3))/5

Combine powers. (2×2 (x - 1) (x + 3) (x + 2) (x + 3))/5 = (2×2 (x - 1) (x + 3)^(1 + 1) (x + 2))/5:

(2×2 (x + 3)^(1 + 1) (x - 1) (x + 2))/5

1 + 1 = 2:

(2×2 (x - 1) (x + 3)^2 (x + 2))/5

2×2 = 4:

Answer: (4 (x - 1) (x + 3)^2 (x + 2))/5

Miko and Raj get the same salary. Every month Miko saves
navik [9.2K]

Answer:

Step-by-step explanation:

The salaries are the same. Only the fraction of how much is saved is quite different.

Equation

x ( 9/11 - 7/9) = 1584

Explanation: The salary amount is x. The fractional amounts saved are also given. You have to take the difference because one of the people saves more than the other.

The amount that is more is 1584.

Solution

9/11 = 0.8182

7/9 = 0.7778

9/11 - 7/9 = 0.8182 - 0.7778 = 0.0404

Put that into the equation.

x(0.0404) = 1584                     Divide by 0.0404)

x(0.0404) = 1584/0.0404        

answer:x = 39204

According to government birth statistics, the probability of a woman
lyudmila [28]

To find the probability of not having twins, we can subtract the probability of having twins from 1. This is because probabilities always add up to 1.

1 - 0.015 = 0.985

The probability of not having twins is 0.985.

Hope this helps!! :)
