First is to know length and width of the rectangular garden. 
length of the garden is difference in the x coordinates
L = 8 - 2 = 6 ft
while the width is the difference in the y coordinates

w = 5 - 3 = 2 ft

now we can solve the area of the rectangular garden.
A = Lw
A = 6 x 2 = 12 sq ft

Cost = ($ 5.25 / 6 sq ft) x ( 12 sq ft)
cost = $ 10.5

Answer:

Average velocity is 32 miles/hr.

Step-by-step explanation:

Given that a particle moves on a line away from its initial position so that after t hours it is  s=6t^2+2t miles from its initial position.

We have to find the average velocity of the particle over the interval [1, 4].

As, average velocity is the change is position over the change in time.

s(4)=6(4)^2+2(4)=104

s(1)=6(1)^2+2(1)=8

∴ \text{Average Velocity=}\frac{s(4)-s(1)}{4-1}

                            =\frac{104-8}{3}=\frac{96}{3}=32miles/hr

Hence, average velocity is 32 miles/hr.

Answer:

  x = 23.1

Step-by-step explanation:

The parallel lines make the left segments proportional to the right segments. This lets us write the equation ...

  x/14 = 33/20

Multiplying by 14, we get ...

  x = 14(33/20) = 7(33/10) = 23.1
