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

Calculate a and b if

const2013 [10]

Notice that

$7^{2014} - 7^{2012} = 7^{2012} \bigg(7^2 - 1\bigg) = 7^{2012} \times 48 = 2^4 \times 3 \times 7^{2012}$

$12=2^2\times3$ , so

$\dfrac{7^{2014}-7^{2012}}{12} = 2^2 \times 7^{2012}$

Then taking the positive square root gives

$\sqrt{\dfrac{7^{2014}-7^{2012}}{12}} = \sqrt{2^2 \times 7^{2012}} = 2\times7^{1006}$

so $\boxed{a=2}$ and $\boxed{b=1006}$ .

A box contains 5 plain pencils and 5 pens. A second box contains 3 color pencils and 5 crayon. One item from each box is chosen

Dmitry_Shevchenko [17]

Hello! :)

What is the probability of choosing a pen from the first box? It is 5/10 = 1/2.

What is the probability of selecting a crayon from the second box? It is 5/8.

The probability of picking a pen from the first box and a crayon from the second box is 5/8 x 1/2 = 5/16.

Hope this helped and I hope I answered in time!

Good luck!

1) Find x, if 1/3 of x is 14

BartSMP [9]

"of" means multiply and "is" means equal

1. $\frac{1}{3}$ x = 14

x = 14(3) multiply both sides by 3 to isolate "x"

x = 42

2. $\frac{1}{5}$ x = 14

x = 14(5) multiply both sides by 5 to isolate "x"

x = 70

3. $\frac{2}{5}$ x = 14

2x = 14(5) multiply both sides by 5

2x = 70

x = 35 divide both sides by 2 to isolate "x"

4. $\frac{7}{8}$ x = 14

7x = 14(8) multiply both sides by 8

7x = 112

x = 16 divide both sides by 7 to isolate "x"
