proof: 2.5*20/100 =50/100 = 0.5

Answer:

2x^2 + 100x +800

1350 ft^2

Step-by-step explanation:

The length of the pool and walkway is x+40

The width of the pool and walkway is x +20+x = 2x+20

Area is length times width

A = (x+40) *(2x+20)

We can FOIL to find the area

first x*2x = 2x^2

outer x*20 =20x

inner 2x*40 = 80x

last = 40*20 = 800

Add these together

2x^2 +20x+80x+800

2x^2+100x+800

b.  x=5

2x^2 + 100x +800

2(5)^2 +100(5) +80

2*25 +500+800

50+1300

1350 ft^2

Answer:

3

Step-by-step explanation:

                                                                                x:5 = 18:30

Convert to the least common denominator     6x:30 = 18 :30

Divide each side by 6                                             6x = 18

                                                                                  x =   3
