Answer:

x= 8.1353

x= 8.135 (rounded to the nearest tenth-thousandths)

x= 8.14 (rounded to the nearest thousandths)

x= 8.1 (rounded to the nearest tenth)

Step-by-step explanation:

<u><em>Note I am not 100% sure with my answer</em></u>

2 − ln (x − 8)= 4

−ln (x − 8) + 2= 4

−ln (x − 8) + 2 + −2= 4 + −2

−ln (x − 8)= 2

−ln (x − 8)/−1= 2/−1

ln (x − 8)= −2

<solve for the logarithm (ln)>

ln (x − 8)= −2

e^ln (x − 8)= e^−2

x − 8= e^−2

x − 8= 0.1353

x − 8 + 8= 0.1353 + 8

x= 8.1353

You are making a walkway around part of a swimming pool. The dimensions of the swimming pool are 18 and 25, while the dimensions
vredina [299]

Answer:

A = 4x^2 + 86x + 450

Step-by-step explanation:

Given

Walkway = x

Length = 18

Width = 25

Required:

The area of the swimming pool

Assume the walkway will be on the 4 sides of the swimming pool.

The total length (L) of the swimming pool will be:

L = 18 + x + x

L = 18 + 2x

The total width (W) will be:

W = 25 + x + x

W = 25 + 2x

The area (A) is:

A = L * W

A = (18 + 2x) * (25 + 2x)

Expand bracket

A = 18 * 25 + 18 * 2x + 25 * 2x + 2x * 2x

A = 450 + 36x + 50x + 4x^2

A = 450 + 86x + 4x^2

Reorder

A = 4x^2 + 86x + 450

You paint one third of a wall and one for seven hours at that rate how long will it take you to paint one wall
Anna [14]
We can put this word problem into an equation.

1/3x = 7

Now we just have to solve for x. To find x we need to multiply by three on both sides.

1/3x = 7
*3       *3
-------------
x = 21

So it will take 21 hours to paint one wall.
