Answer:

6x² + 9x + 2

Step-by-step explanation:

The pool is a square with a side length of 2x.

The area of the pool = length * length = 2x * 2x = 4x²

The area of the deck surrounding the pool has length of 2x + 1 and width of 5x + 2. Therefore:

The area of the deck surrounding the pool = length * width = (2x + 1)(5x + 2) = 10x² + 4x + 5x + 2 = 10x² + 9x + 2

Area of the deck only = area of the deck surrounding the pool - area of pool =  (10x² + 9x + 2) - 4x²

Area of the deck only = 6x² + 9x + 2

What are the coordinates of R' for the dilation D(0.5. p)(PQRS)?
11111nata11111 [884]

Answer:

R' = (-1,-0.5)

Step-by-step explanation:

See attachment for complete question.

From the attachment:

P = (-3,-3)

R = (1,2)

Dilation:

D_{(0.5,P)}

Required

Determine R'

First, subtract the coordinates of P from R. This means that R is measured from P.

R = (1-(-3),2-(-3))

R = (1+3,2+3)

R = (4,5)

Next, apply dilation factor 0.5

R' = R * 0.5

R' = (4,5) * 0.5

R' = (4* 0.5,5* 0.5)

R' = (2,2.5)

Lastly, measure R' from the origin by adding the coordinates of P to R'

R' = (2+(-3),2.5+(-3))

R' = (2-3,2.5-3)

R' = (-1,-0.5)
