Answer:

  4(x-2)(x-1)^3(x+1)\sqrt{x-1}

Step-by-step explanation:

4x(x-1)^{9/2}-8(x-1)^{7/2}=4(x-1)^{7/2}(x(x-1)^{2/2} -2)=4(x-1)^{7/2}(x^2-x-2)\\\\=4(x-1)^{7/2}(x-2)(x+1)=4(x-2)(x-1)^3(x+1)\sqrt{x-1}

___

Among other things, the leading coefficient cannot be 2, as 4 is a factor of both the given terms.

Brums [2.3K]

Answer:

Assuming you're asking for the value of x, the answer would be 4.

Step-by-step explanation:

2(4 + 4)

2(8) = <u>16</u>

4(4) + 3 - 2(4) + 5

4 * 4 = 16

2 * 4 = 8

16 + 3 - 8 + 5

16 + 3 = 19

19 - 8 = 11

11 + 5 = <u>16</u>

16 = 16

Here are two squares, A and B. A B The length of each side of square B is 4cm greater than the length of each side of square A.
alina1380 [7]

Answer:

144cm²

Step-by-step explanation:

Area of square A Aa = La²

Area of square B  Ab= Lb²

If the length of each side of square B is 4cm greater than the length of each side of square A, then;

Lb =  La + 4 ... 1

Also if the area of square B is 70cm² greater than the area of square A, then;

Ab = Aa + 70

Since Aa =  La² and Ab =  Lb²

Lb² = La² + 70 ...2

Substitute 1 into 2;

(La+4)² = La²+70

Expand

La²+8La+16 = La²+80

8La+16 = 80

8La = 80 - 16

8La = 64

La = 64/8

La = 8cm

Since Lb = La + 4

Lb = 8 + 4

Lb = 12cm

Area of square B = Lb²

Area of square B = 12²

Area of square B = 144cm²

In 1999, the share price for General Motors stock was $144 per share but has been declining at an average rate of 14% per year.
vodomira [7]

Answer:  $5.22  (in the year 2021)

========================================================

Explanation:

The year 2021 is 22 years after 1999 since

2021 - 1999 = 22

That means we'll plug x = 22 into the equation given to us

P = 144*(0.86)^x

P = 144*(0.86)^22

P = 5.21588994768589 which is approximate

P = 5.22 rounding to the nearest cent

The share price is about $5.22 in the year 2021.

This assumes that the 14% decline keeps happening year after year; however, in reality, stocks are more complicated and fluctuate more randomly if anything.
