shusha [124]

Answer:

5a. 4w+24≤100

5b. Dimensions=31ft x 19 ft

      Area = 589ft²

Step-by-step explanation:

l=w+12

p=2l+2w

p=2(w+12)+2w

p=2w+24+2w

p=4w+24

The farmer has 100ft of fencing, so maximum that the perimeter (p) can be is 100, meaning (4w+24) has to be less than or equal to 100:

4w+24≤100

For the largest possible perimeter, all 100 of fencing will be used, so allow 100 to be equal to 4w+24)

100=4w+24

4w=76

w=19ft

l=w+12

l=19+12

l=31ft

The dimensions are 31ft x 19ft.

Area=lw

=31*19

=589ft²

If I put this into an equation it would look like 2x+2= 66. 66-2= 64. You do this because to get x you have to reverse the equation, but you have to do the number not connected to x first. Then 2x= 64. So you divide 64 by 2 which is 32. So Jordan is 32 years old. Hope this helped!
